mac80211: rework mac address allocation
If the first byte is available in the address mask, use only that one -
set the local bit and xor it with the id << 2. This ensures that there
are no hardware BSSID & BSSID-mask conflicts with devices that have
almost the same MAC address with just a small offset. The MAC address
conflict has been observed in a deployment with some devices from the
same batch when running with multiple interfaces.
If only some bits of the last byte are available, xor the id onto the
last MAC address byte (relevant mostly for Ralink devices).
In other cases (should not happen at this point), use the previous MAC
address offset calculation but without the local bit.
