mac802154: iface: fix hrtimer cancel on ifdown
The interframe spacing timer is a per phy definition and is part of a ieee802154_local structure. If we have possible multiple interfaces ifdown one interface then the timer should not be cancled. First if the last interface is down and the receive handling is stopped we should be sure that the interframe spacing timer isn't run anymore.
