    If a _guessed_ compression method fails, it is never PROTOCOL_WARN.
    
    Rationale: When use a guessed compression method, we already gave a
    PROTOCOL_WARN when our guess differed from the declared method,
    AND we gave a PROTOCOL_WARN when the declared method failed.  It is
    not a protocol problem that the guessed method failed too; it's just
    a recovery attempt that failed.
