cfg80211: fix NULL ptr deref
commit 211a4d12abf86fe0df4cd68fc6327cbb58f56f81 Author: Johannes Berg <johannes@sipsolutions.net> Date: Tue Oct 20 15:08:53 2009 +0900 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.
