[PATCH] nl80211: Register eloop after hs20 action frame

[Eduardo Abinader]

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.
