[PATCH 2/2] ath5k: fix CAB queue operation

[Bob Copeland <me@bobcopeland.com>]

We need to process tx descriptors for all queues (currently main tx
queue and cabq) which may have triggered the TX completion interrupt.
Otherwise, the queues can get stuck after sending a few frames.

John, hand-edited this one to remove the queue config stuff for now.
