Sam Leffler 61063e478a Defer state change on disassociate to avoid unnecessarily dropping the
lease: track the current bssid and if it changes (as reported in an
assoc/reassoc) event only then kick the state machine.  This gives us
immediate response when roaming but otherwise causes us to fallback on
the normal state machine.
