ath5k: disable beacon interrupt when interface is down
When we remove the active interface, there's no need to continue sending beacons; doing so would cause a null pointer deref in ieee80211_beacon_get(). Disable the interrupt in remove_interface and add a WARN_ON(!vif) in case there are other instances lurking. Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: John W.
