[PATCH 2.6.35] cfg80211: fix can_beacon_sec_chan, reenable HT40
From: Mark Mentovai <mark(a)moxienet.com>
commit 09a02fdb919876c01e8f05960750a418b3f7fa48 upstream.
Fixes 2.6.35.9 -> 2.6.35.11 regression:
https://bugzilla.redhat.com/show_bug.cgi?id=671514
This follows wireless-testing 9236d838c920e90708570d9bbd7bb82d30a38130
("cfg80211: fix extension channel checks to initiate communication") and
fixes accidental case fall-through. Without this fix, HT40 is entirely
blocked.
