Fix a recently introduced iwn(4) problem where the link gets stuck since
every CCMP encrypted frame is discarded by the AP as a replay.
This happened because of CCMP frames with out of range PNs sent by hardware.
It seems iwn firmware doesn't like it if we reset the Tx scheduler slot for
a frame which is still within the firmware's block ack window, even if the
frame has already been ACKed. So frames now get cleared off the Tx queue
only when the block ack window has moved past them, which is good enough and
seems to prevent the problem.
Problem reproduced and fix tested by both myself and jca@
