mac80211: disable beacons before removing the associated interface
When downing interfaces, it's a good idea to tell the driver to
stop sending beacons; that way the driver doesn't need special
code in ops->remove_interface() when it should already handle the
case in bss_info_changed().
This fixes a potential crash with at least ath5k since the vif
pointer will be nullified while beacon interrupts are still active.
