When an AP disassociates us, we currently go into a weird state because the SME doesn't handle authenticated but not associated well unless it's within its own state machine, it can't recover from that. However, it shouldn't need to, since we don't do any decisions in it really -- so when we get disconnected, simply deauthenticate too.
