cfg80211: fix bugs in new SME implementation
When splitting the SME implementation from the MLME code,
I introduced a few bugs:
* association failures no longer sent a connect-failure event
* getting disassociated from the AP caused deauth to be sent
but state wasn't cleaned up, leading to warnings
* authentication failures weren't cleaned up properly, causing
new connection attempts to warn and fail
Fix these bugs.
