ezusb_read_ltv() is always invoked via the ->read_ltv() callback. This callback is mostly invoked under orinoco_lock() which disables BH. There are a few invocations during probe which occur in preemptible context via: ezusb_probe() -> orinoco_init() -> determine_fw_capabilities() Extend `hermes_ops' with the ->read_ltv_pr callback which is implemented with the same callback like ->read_ltv on `hermes_ops_local'. On `ezusb_ops' ->read_ltv is used for callbacks under the lock which need to poll. The new ->read_ltv_pr() is used in the preemptible context in which it is possible to wait for the completion. Provide HERMES_READ_RECORD_PR() and hermes_read_wordrec_pr() which behave like their non _pr equivalents and invoke ->read_ltv_pr(). This removes the last user of ezusb_req_ctx_wait() and can now be removed.
