    lib: Fix crash when adapter/device store is destroyed
    
    Patch 17983ace (lib: Use GDBusObjectManager) changes the logic of
    device_add and adapter_add so that the device/adapter object is passsed
    in. Because of that the object must not be unref'ed anymore, as it is
    owned by the surrounding code (i.e. GDBusObjectManager).
