gdbus: Avoid reporting GDBusClient disconnect twice 

No matter if disconnection was reported previously, g_dbus_client_unref()
was always calling service disconnect callback. This patch fix the
following scenario:
1) service disconnects from the bus
2) disconnect callback gets called
3) client calls g_dbus_client_unref(), disconnect callback is called
   again.
