cfg80211: send events for userspace SME

When the userspace SME is in control, we are currently not sending
events, but this means that any userspace applications using wext
or nl80211 to receive events will not know what's going on unless
they can also interpret the nl80211 assoc event. Since we have all
the required code, let the SME follow events from the userspace
SME, this even means that you will be refused to connect() while
the userspace SME is in control and connected.
