Subject[031/107] wireless: Reset beacon_found while updating regulatory
2.6.32-longterm review patch.  If anyone has any objections, please let us know.

------------------
From: Rajkumar Manoharan <rmanohar@qca.qualcomm.com>

commit aa3d7eef398dd4f29045e9889b817d5161afe03e upstream.

During the association, the regulatory is updated by country IE
that reaps the previously found beacons. The impact is that
after a STA disconnects *or* when for any reason a regulatory
domain change happens the beacon hint flag is not cleared
therefore preventing future beacon hints to be learned.
This is important as a regulatory domain change or a restore
of regulatory settings would set back the passive scan and no-ibss
flags on the channel. This is the right place to do this given that
it covers any regulatory domain change.
