mac80211: disable powersave for broken APs
Only AID values 1-2007 are valid, but some APs have been found to send random bogus values, in the reported case an AP that was sending the AID field value 0xffff, an AID of 0x3fff (16383). There isn't much we can do but disable powersave since there's no way it can work properly in this case.
