wifi: ath5k: fix an off by one check in ath5k_eeprom_read_freq_list()

Browse Source 
[ Upstream commit 4c856ee12d ]

This loop checks that i < max at the start of loop but then it does
i++ which could put it past the end of the array.  It's harmless to
check again and prevent a potential out of bounds.
