SVN rev 222679 on 2011-06-04 11:43:09Z by bschmidt
The firmware of 4965 series adapters seems to die while trying to send
probe requests at 1Mbps while being associated on a 5GHz channel. Sending
those at 6Mbps does work, so use that instead during a background scan.
This workaround allows us to re-enable background scan support for the
4965 adapters.
Also, just enabling one antenna on 5GHz results in better reception of
beacons:

vs
test 00:26:5a:c6:14:1a 40 54M -92:-95 200 E WME HTCAP ATH
Due to roam:rssi thresholds set to 7 by default it might have been
impossible to associate to that network. While here use
IEEE80211_IS_CHAN_5GHZ() to determine the band.
