ath9k: fix false positives in the baseband hang check

ath9k_hw_check_alive() occasionally returns false, as the hardware
is still processing data in a specific state. Fix this issue by
repeating the test a few times with longer delay inbetween attempts.
This gets rid of excessive hardware resets that appear frequently on
some AR9132 based devices, but could also happen on AR9280.
