    gstplayer: Fix loading state partial handling
    
    Commit a7c0180c introduced a LOADING state when a new song is
    loaded. However, the change was only defined in state setter and not
    the getter.
    
    Add LOADING state support to _get_playback_status method.
    Resset SmoothScale value to zero when a new song is loaded.
