[PATCH 1/7] nl80211: Always register managment frames handler

[Ilan Peer]

From: Avraham Stern <avraham.stern at intel.com>

If registering WMM-AC ADDTS response action frame or WMM-AC DELTS
action frame fails, the managment frame handler is not being
registered. This results with a segmentation fault when trying to
unsubscribe the handler when the interface is removed.
Fix it by always registering the handler and just returning a negative
value to note that the action frame could not be registered.

This patch should be squashed with the patch: "nl80211: implement
add_ts/del_ts ops".
