Subject: [ 31/69] iwlwifi: unregister LEDs if mac80211 registration fails

3.2-stable review patch.  If anyone has any objections, please let me know.

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

From: Johannes Berg <johannes.berg@...el.com>

commit 0e1fa7ef25004b9c1a14147bce61c15c2f1c6744 upstream.

Otherwise the LEDs stick around and cause issues the
next time around since they're still there but not
really hooked up.
