On an open AP when you pull the plug on the AP, if we are not already in
BMPS mode then the firmware will not generate a disconnection event.
Instead we need to monitor for failure to enter BMPS and treat a string of
failures as connection loss.
Secure AP connections don't appear to demonstrate this behavior so the
work-around is limited to open APs only.
