    Fix KDC crash when logging PKINIT enctypes
    
    Commit a649279727490687d54becad91fde8cf7429d951 introduced a KDC crash
    bug due to transposed strlcpy() arguments.  Fix the argument order.
    
    This bug does not affect any MIT krb5 release, but affects the Fedora
    krb5 packages due to backports.  CVE-2019-14844 has been issued as a
    result.
