Add BAW state tracking to ensure I'm updating the BAW before freeing
the ath_buf.

Add locking around the BAW related code. Since the BAW can be modified
by both net80211/ifnet context (ie interface TX) as well as the ath
task (frame scheduling & completion), it needs to be locked.
A node purge during active traffic could leave the BAW inconsistent.

This has fixed some immediate issues with the TX hanging, but it hasn't
fully fixed things.
