cfg80211: report userspace SME connected event properly

Browse Source 
Instead of hacking the event reporting into the
__cfg80211_connect_result() function which is also
invoked by others, set up things correctly and then
invoke that function, so that it can do more sanity
checking.

Also, it is currently not possible to get a ROAMED
event from the userspace SME anyway since we send
out a DISCONNECTED event when it disassociates and
then a new CONNECTED event on the next association.

Thanks to Zhu Yi for pointing out that the code is
somewhat convoluted and doesn't warn when it should.
