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.)

fd06b53774 Don't unlock mutex in interrupt thread (except for wpi_rx_done() - for now) - 
fixes various races between wpi_notif_intr() and wpi_stop_locked().

(attachment 154381)

Committers note: yes, unlock/if_input/lock has to go away, but that'll
have to be done later.
