rt2x00: Don't enable broad- and multicast buffering on USB devices
Since rt2x00 USB devices have no chance to know when a beacon was sent
out in AP mode currently all broad- and multicast traffic is buffered in
mac80211 but never sent out at all.
Unfortunately we have no chance in sending the traffic out after a
DTIM beacon due to hw limitations. Hence, instead of never sending the
buffered traffic out better send it out immediately.
