[PATCH BlueZ] core: Do not change service state in btd_service_connect if it fails

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

If .connect fails and the service state changes it may re-enter
connect_next, inverting the order and messing up the error of each
connect request.
