Johannes Berg f1f2e068bb wifi: iwlwifi: pcie: synchronize IRQs before NAPI 
[ Upstream commit 37fb29bd1f90f16d1abc95c0e9f0ff8eec9829ad ]

When we want to synchronize the NAPI, which was added in
commit 5af2bb3168 ("wifi: iwlwifi: call napi_synchronize()
before freeing rx/tx queues"), we also need to make sure we
can't actually reschedule the NAPI. Yes, this happens while
interrupts are disabled, but interrupts may still be running
or pending. Also call iwl_pcie_synchronize_irqs() to ensure
we won't reschedule the NAPI.
