ath9k: make sure main_rssi is positive
some times the rssi control descriptor for the main antenna may be
negative like that of alternate antenna, hence before incrementing
packet counts/rssi of main/alternate antenna make sure both main_rssi
and alt_rssi are positive only. this avoids wrong selection of antenna
due to diversity
