lets not go off in the weeds for the wrong things now.  The answer to
the retry is at most one time.  The first time would be blocked, then
the suspend enable would need to re-enabled under user mode control that
would, buy that time, know it has to ack to the modem to stop rejecting
the suspend attempt.
