mac80211: send (QoS) Null if no buffered frames
For PS-poll, there's a possible race between
us expiring a frame and the station polling
for it -- send it a null frame in that case.
For uAPSD, the standard says that we have to
send a frame in each SP, so send null if we
don't have any other frames.
