Subject[PATCH 3.2 28/92] rt2x00: fix beaconing on USB
3.2.60-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Stanislaw Gruszka <sgruszka@redhat.com>

commit 8834d3608cc516f13e2e510f4057c263f3d2ce42 upstream.

When disable beaconing we clear register with beacon and newer set it
back, what make we stop send beacons infinitely.
