ath9k_htc: Drain pending TX frames properly
When doing a channel set or a reset operation the pending
frames queued up for transmission have to be flushed and
sent to mac80211. Fixing this has to be done in two separate
steps:
* Flush queued frames and kill the URB TX completion handler.
* Complete all the frames that in the TX pending queue.
This patch adds proper support for draining and all the callsites
namely, channel change/reset/idle/stop are fixed. A separate queue
is used for handling failed frames.
