"ath0: device timeout" when environment is clear

[Adrian Chadd]

Hi,

The lack of TX buffers in that list (they're all RX buffers) means that the
TX queue is empty.

So, the "device timeout" is incorrect - the device didn't timeout, we just
didn't queue any frames to the device but somehow the TX watchdog was set.
Or, the watchdog wasn't cleared upon TX queue processing.

I wonder why this is occuring. ;-)
