mac80211: fix LED in idle handling
feng xiangjun reports that my commit 382a103b2b528a3085cde4ac56fc69d92a828b72 Author: Johannes Berg <johannes.berg@intel.com> Date: Fri Mar 22 22:30:09 2013 +0100 mac80211: fix idle handling sequence broke the wireless status LED. The reason is that we now call ieee80211_idle_off() when the channel context is assigned, and that doesn't recalculate the LED state. Fix this by making that function a wrapper around most of idle recalculation while forcing active.
