ath9k: fix stopping tx dma on reset
In some situations, stopping Tx DMA frequently fails, leading to messages
like this:
ath: Failed to stop TX DMA in 100 msec after killing last frame
ath: Failed to stop TX DMA!
This patch uses a few MAC features to abort DMA globally instead of iterating
over all hardware queues and attempting to stop them individually.
Not only is that faster and works with a shorter timeout, it also makes the
process much more reliable.
With this change, I can no longer trigger these messages on AR9380,
and on AR9280 they become much more rare.
