WPS: Make sure reconfiguration timeout is not left behind on deinit

Even though this is a short timeout, it is at least theoretically
possible for the interface to be removed while waiting for
reconfiguration to start. Avoid issues with this by cancelling the
timeout on any WPS interface deinit. In theory, this should be postponed
until interface removal, but that does not fit very nicely to the
current wps_hostapd.c style.
