ath9k: Fix buffer overflow error
The commit "ath9k: stomp audio profiles on weak signal
strength" failed to take care of new stomp type while
programming concurrent tx priority. That leads to array
index out of bounds access.
drivers/net/wireless/ath/ath9k/btcoex.c:414
ath9k_hw_btcoex_set_concur_txprio()
error: buffer overflow 'stomp_txprio' 4 <= 4
