Looks like at least one of the problems (or symptoms) is that the
wpa_driver_nl80211_associate call is returning -EEXIST when
supplicant is trying to associate.

I'm wondering if perhaps too many events are in the event
queue, and perhaps we are processing them too late to
be valid.  Going to add some code to try to verify
if that is the cause or not...
