Clear profile connnection status of bonded devices when BT is turned off

When BT is turned off in mid of a profile connection, sometimes
profile connection status change message with status= DISCONNECTED
does not reach Settings app which results in stale connection status
for the device when BT is enabled next time. Fixed the issue
By explicitly clearing the connection status for all paired devices
when BT is turning OFF
