    setfullscreen: don't process the property twice
    
    Some clients try to set _NET_WM_STATE_FULLSCREEN even when the window is
    already in fullscreen.
    For example, c->oldstate was set two times in a raw and window would
    then always be floating.
    We must check that it's not the case before processing it.
