nl80211: Register eloop after hs20 action frame

Even when hs20 action frame is unable to be registered,
for whatever reason, it should be possible to register
event handle for received driver messages. This patch also
avoids a segmentation fault, when p2p and hs20 were enabled
and GO NEG was unable to create p2p iface, the destroy eloop
was crashing by reading an invalid handle.
