atheros: use get_unaligned_le*() for bssid mask setting
Historically some macro helpers have been users for this,
AR5K_LOW_ID() and AR5K_HIGH_ID(), use upstream unaligned
helpers instead. This applid to ath5k and ar9170. ath9k
already uses this.
Worth noting is ath5k uses an ah_sta_id but that is already
the MAC address combined with the associaiton ID, ah_sta_id
is really ETH_ALEN in size.
