WNM: Ignore WNM-Sleep Mode Response without pending request
Commit 03ed0a52393710be6bdae657d1b36efa146520e5 ('WNM: Ignore WNM-Sleep
Mode Response if WNM-Sleep Mode has not been used') started ignoring the
response when no WNM-Sleep Mode Request had been used during the
association. This can be made tighter by clearing the used flag when
successfully processing a response. This adds an additional layer of
protection against unexpected retransmissions of the response frame.
