    gobject: Avoid redundant atomics
    
    According to the commit that introduced these
    calls (4b334ef8f1393c997a2d83d), we are checking
    the refcount here to avoid calling g_object_ref
    when the refcount is 0, in the rare case that
    notification would be triggered during finalize.
    
    But we are now freezing notifications during
    finalize, and after recent changes, we no longer call
    g_object_ref for notification while a freeze is
    in place.
