Subject: [PATCH] mac80211: cancel restart_work explicitly instead of depending
 on flush_scheduled_work()

iee80211_hw->restart_work is the only work which uses the system
workqueue.  Instead of calling flush_scheduled_work() during
iee80211_exit(), cancel the work during unregistration.

This is to prepare for the deprecation and removal of
flush_scheduled_work().
