    wayland/surface: Clear shadow width when hiding
    
    Not doing this means the next time the same surface is shown, if the
    shadow size wasn't changed, it wouldn't be sent to the compositor, which
    then would result in compositor deriving its own window geometry which
    would include the shadow margin.
    
    This fixes an issue where the file chooser dialog would grow each time
    it opened.
