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.
