Use TX control flag IEEE80211_TX_CTL_ASSIGN_SEQ as a request to update
the seq# for the frames. This will likely require some further cleanup
to get seq# correctly for Beacons vs. other frames and also potentially
for multiple BSSes. Anyway, this is better than ending up sending out
most frames with seq# 0.

of trying to allocate a single Beacon frame and then update it. In
addition, the remaining ath_skb_{map,unmap}_single() wrapper calls are
replaced with direct pci_{map,unmap}_single() calls in beacon.c. Power
save buffering for multicast/broadcast frames is not yet converted to
use mac80211-style (frames to be buffered inside mac80211, not in
driver).
