If a MCU timeout occurs before a hw restart completes, another hw restart
is scheduled, and the station state gets corrupted.
To speed up dealing with that, do not issue any MCU commands after the first
timeout, and defer handling timeouts until the reset has completed.
Also ignore errors in MCU commands during start/config to avoid making user
space fail on this condition. If it happens, another restart is scheduled
quickly, and that usually recovers the hardware properly.

mac80211 .start(), .stop() callbacks are never called concurrently with
other callbacks. The only concurencly is with mt76 works which we cancel
on stop() and schedule on start().
This fixes possible deadlock on cancel_delayed_work_sync(&dev->mac_work)
as mac_work also take mutex.
