The firmware code cannot cope with requests to remove BSS indices that have
not previously been added. This primarily happens when the device is
suspended and then resumed. ieee80211_reconfig() then calls into
wcn36xx_bss_info_changed() with an empty bssid and BSS_CHANGED_BSSID set,
which subsequently leads to a firmware crash:
[ 43.647928] qcom-wcnss-pil a204000.wcnss: fatal error received: halMsg.c:4964:halMsg_DelBss: Invalid BSSIndex 0
[ 43.647959] remoteproc remoteproc0: crash detected in a204000.wcnss: type fatal error
To fix this, set bss_index to WCN36XX_HAL_BSS_INVALID_IDX for all bss
that have not been configured in the firmware, and don't call into the
firmware with invalid indices.

When wcn36xx_dxe_tx_frame() fails to transmit the TX frame, the driver
will call into ieee80211_free_txskb() for the skb in flight, so it'll no
longer be valid. Hence, we shouldn't keep a reference to it in ctl->skb.
Also, if the skb has IEEE80211_TX_CTL_REQ_TX_STATUS set, a pointer to
it will currently remain in wcn->tx_ack_skb, which will potentially lead
to a crash if accessed later.
Fix this by checking the return value of wcn36xx_dxe_tx_frame(), and
nullify wcn->tx_ack_skb again in case of errors. Move the assignment
of ctl->skb in wcn36xx_dxe_tx_frame() so it only happens when the
transmission is successful.

wcn36xx_start_tx function retrieves the buffer descriptor from the
channel control queue to start filling tx buffer information. However,
nothing prevents this same buffer to be concurrently accessed in a
concurent tx call, leading to potential buffer coruption and firmware
crash (observed during iperf test). The channel control queue should
only be accessed and updated with the channel lock.
Fix this issue by using a local buffer descriptor which will be copied
in the thread-safe wcn36xx_dxe_tx_frame.
Note that buffer descriptor size is few bytes so the introduced copy
overhead is insignificant. Moreover, this allows to keep the locked
section minimal.

When attempt to run worker (ath10k_sta_rc_update_wk) after the station object
(ieee80211_sta) delete will trigger the kernel panic.
This problem arise in AP + Mesh configuration, Where the current node AP VAP
and neighbor node mesh VAP MAC address are same. When the current mesh node
try to establish the mesh link with neighbor node, driver peer creation for
the neighbor mesh node fails due to duplication MAC address. Already the AP
VAP created with same MAC address.
It is caused by the following scenario steps.
Steps:
1. In above condition, ath10k driver sta_state callback (ath10k_sta_state)
fails to do the state change for a station from IEEE80211_STA_NOTEXIST
to IEEE80211_STA_NONE due to peer creation fails. Sta_state callback is
called from ieee80211_add_station() to handle the new station
(neighbor mesh node) request from the wpa_supplicant.
2. Concurrently ath10k receive the sta_rc_update callback notification from
the mesh_neighbour_update() to handle the beacon frames of the above
neighbor mesh node. since its atomic callback, ath10k driver queue the
work (ath10k_sta_rc_update_wk) to handle rc update.
3. Due to driver sta_state callback fails (step 1), mac80211 free the station
object.
4. When the worker (ath10k_sta_rc_update_wk) scheduled to run, it will access
the station object which is already deleted. so it will trigger kernel
panic.
Added the peer exist check in sta_rc_update callback before queue the work.
