For the profile connection initiated by remote device,
ext_connect() function is triggered without advance the state
of device's service to BTD_SERVICE_STATE_DISCONNECTING.
This is causing a problems when the later 'NewConnection'
dbus method call is made to registered application. If
the remote device gets disconnected during the period of
time waiting for the reply of 'NewConnection' method, the
btd_service_disconnect() call will fail at the service state
check and never handle the profile disconnection due to that
state was incorrectly left as BTD_SERVICE_STATE_DISCONNECTED.
Fix the problem by adding additional call in ext_connect()
to assure the service state has changed. Also modify the logic
of service state check in btd_service_connecting_complete()
to prevent the problem when the 'NewConnect' reply changes
service state to BTD_SERVICE_STATE_CONNECTED while the device
has already disconnected before it arrives.
