More BAR related stuff, which is partially locking related stuff.

* Pause/unpause the queue when BAR TX is complete.

  The problem is that we're not notified when a BAR TX times out
  and the TX won't happen again - the session is just torn down.
  So, to work around the API shortcomings for now, hard-code it
  to cause an unpause at retry == 50.

  This only works if the hardware _DOES_ call the callback upon
  frame TX failure. If the callback never gets called, this will
  all fall in a heap. Luckily, ath will.

* Fix locking around TXQ pause/resume calls, as they can occur from
  the upper layers. This isn't entirely complete, as I'm not
  similarly locking the pause/resume checks in the rest of the
  code. I'll do that soon.

* Only pause the TID if the ieee80211_send_bar() call was successful.

This now seems to work fine with TX packet loss in non-aggregate mode,
but I'm not yet convinced that I'm sending the correct sequence
number in the BAR frame. I'll look at that next.
