From: Johannes Berg <johannes.berg@xxxxxxxxx>
Through races, a packet may be enqueued for
transmission to a station while that station
is going to sleep, in which case the warning
here triggers. Instead of warning, check the
condition -- if this packet is not a PS-poll
response then we still enqueue it but it will
be rejected by the device since the station
is marked as asleep.
