ath5k: move reset to mac80211 workqueue

Browse source

We currently trigger a reset via a tasklet when certain error
conditions are detected so that the card will (eventually)
restart.  Unfortunately this makes locking complicated since
reset can also be called in process context (e.g. for channel
change).  Currently nothing protects against concurrent resets,
which can be the source of corruption bugs.

Reset takes too long to spinlock the whole thing, so this
patch moves deferred resets into the mac80211 workqueue to
enable use of sc->lock mutex.
