mac80211: cancel restart_work in ieee80211_unregister_hw
Unlike most other workqueue-tasks, the restart_work is not scheduled onto mac80211's private per-interface workqueue, but onto one of the system-wide workqueues. Therefore the mac80211-stack has to cancel any pending restarts, before destroying the shared device context and handing back the memory. Otherwise - under very unlucky circumstances - there could be a stale work- item left, because some other kernel component might have delayed the execution of ieee80211_restart_work for too long.
