cfg80211: really ignore the regulatory request
At the beginning of wiphy_update_regulatory() a check is performed
whether the request is to be ignored. Then the request is sent to
the driver nevertheless. This happens even if last_request points
to NULL, leading to a crash in the driver:

Fix this by returning early. Also remove the out: label as it is
not any longer needed.
