    More LOG_PROTOCOL_WARN.
    
    Make origin-side messages about padding negotiation failure into
    LOG_PROTOCOL_WARN.
    
    I'm not sure I like this either.. But the negotiation refusal case might
    happen naturally due to consensus drift, and is functionally no different than
    a corrupted cell.
