mac80211: use fixed broadcast address
The netdev broadcast address cannot change from all-ones so there's no need to use it; we can instead hard-code it. Since we already have an instance in tkip.c, which will be shared if it is marked static const, doing this reduces text size at no data/bss cost. The real motivation for this is, of course, the desire to get rid of almost all uses of netdevs in mac80211 so that auditing their use becomes easier.
