Subject: [086/104] mac80211: fill rate filter for internal scan requests

3.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Simon Wunderlich <simon.wunderlich@...03.tu-chemnitz.de>

commit c72e8d335e2c6a309b6281f2abcf491f37b8b92b upstream.

The rates bitmap for internal scan requests shoud be filled,
otherwise there will be probe requests with zero rates supported.
