e2ad437112 Add a new taskqueue (device specific, not net80211 ic->tq); use it for 
device restart.

(Committers note - once scan overhaul and a few other things have been
fixed in net80211 to not block things in the taskqueue, this can disappear
and the device specific taskqueues in other drivers can also go away.)
