ath9k: Fix ath_print in xmit for hardware reset.

ath_print in xmit.c should say "Reseting hardware"
instead of Resetting HAL!(since HAL is being fazed out).
dmesg shows:
[ 8660.899624] ath: Failed to stop TX DMA in 100 msec after killing last frame
[ 8660.899676] ath: Unable to stop TxDMA. Reset HAL!
