    Use protocol error for PKINIT cert expiry
    
    If we fail to create a cert chain in cms_signeddata_create(), return
    KRB5KDC_ERR_PREAUTH_FAILED, which corresponds to a protocol code,
    rather than KRB5_PREAUTH_FAILED, which doesn't.  This is also more
    consistent with other error clauses in the same function.
