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.
