mac80211: don't attempt to reorder multicast frames
Multicast frames can't be transmitted as part of an aggregation session (such a session couldn't even be set up) so don't try to reorder them. Trying to do so would cause the reorder to stop working correctly since multicast QoS frames (as transmitted by the Aruba APs this was found with) would cause sequence number confusion in the buffer.
