2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: Luis R. Rodriguez <lrodriguez@atheros.com>

commit 3bc3c0d748402e8c1f31b8569f5924d25d7b8e30 upstream.

The beacon monitor should be disabled when going off channel
to prevent spurious warnings and triggering connection
deterioration work such as sending probe requests. Re-enable
the beacon monitor once we come back to the home channel.

This patch has fixes for stable kernels [2.6.34+].
