4a0e78ec55 Change three methods in struct ieee80211com, namely ic_updateslot, 
ic_update_mcast and ic_update_promisc, to pass pointer to the ieee80211com,

f67a4dcfd7 Make net80211 drivers supply their device name to the net80211 layer, so 
that the latter doesn't need to go through struct ifnet to get their name.

88f71e0aa9 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.)

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.
