[gnome-shell] cleanup: Don't call method via a parent's prototype

[Georges Basile Stavracas Neto <gbsneto src gnome org>]

    cleanup: Don't call method via a parent's prototype
    
    We cannot disconnect a signal handler via the usual disconnect() as
    nm_device_disconnect() shadows the GObject method, but we can use
    g_signal_handler_disconnect().
