    spice: handle client disconnect gracefully
    
    If the client (spice-gtk) disconnects e.g. during a file transfer,
    the mux stream gets closed and the count of read bytes does not
    match the count that the client previously announced.
    However, in this case, we mustn't simply return, since that would
    prevent any further connections.
