[gtk/3-24-warn-fixes: 5/5] sw: Do not cast clear function in g_clear_pointer()

    sw: Do not cast clear function in g_clear_pointer()
    
    We don't need to do it, since g_clear_pointer() will do it for us, and
    will also check if the function conforms to a GDestroyNotify. Using an
    explicit cast will generate a compiler warning.
