wireless : use a dedicated workqueue for cfg80211.
This patch moves the works cleanup, scan and events to a cfg80211 dedicated workqueue. Platform driver like eeepc-laptop ought to use works to rfkill (as new rfkill does lock in rfkill_unregister and the platform driver is called from rfkill_switch_all which also lock the same mutex). This raise a new issue in itself that the work scheduled by the platform driver to the global worqueue calls wiphy_unregister which flush_work scan and event works (which thus flush works on the global workqueue inside a work on the global workqueue) and also put on hold the wdev_cleanup_work (which prevents the dev_put on netdev thus indefinite Usage count error on wifi device).
