Subject: [PATCH v2] ath9k:  Add wiphy name to log messages.

From: Ben Greear <greearb@...delatech.com>

On systems with multiple NICs, it's nice to know which
one is producing warnings.  Here is an example of the
new ouput:

ath: wiphy0: Failed to stop TX DMA, queues=0x005!

Signed-off-by: Ben Greear <greearb@...delatech.com>

v2:  Remove _ath_printk macro, minor formatting changes.
