cfg80211: fix NULL ptr deref

cfg80211: sme: deauthenticate on assoc failure
introduced a potential NULL pointer dereference that
some people have been hitting for some reason -- the
params.bssid pointer is not guaranteed to be non-NULL
for what seems to be a race between various ways of
reaching the same thing.
While I'm trying to analyse the problem more let's
first fix the crash. I think the real fix may be to
avoid doing _anything_ if it ended up being NULL, but
right now I'm not sure yet.
I think
http://bugzilla.kernel.org/show_bug.cgi?id=14342
might also be this issue.
