cfg80211/mac80211: avoid bounce back mac->cfg->mac on sched_scan_stopped
When sched_scan_stopped was called by the driver, mac80211 calls
cfg80211, which in turn was calling mac80211 back with a flag
"driver_initiated". This flag was used so that mac80211 would do the
necessary cleanup but would not call the driver. This was enough to
prevent the bounce back between the driver and mac80211, but not
between mac80211 and cfg80211.
To fix this, we now do the cleanup in mac80211 before calling
cfg80211. To help with locking issues, the workqueue was moved from
cfg80211 to mac80211.
