[PATCH v2 2/2] crypt32: Properly check root certificate in CERT_CHAIN_REVOCATION_CHECK_CHAIN.

[Zhiyi Zhang]

Original patch by Michael Müller.

Root certificates don't have CRL Distribution Point or Authority Info Access field.
Don't report error with CERT_CHAIN_REVOCATION_CHECK_CHAIN in CertGetCertificateChain()
because of this.

Signed-off-by: Zhiyi Zhang

v2: ignore CRYPT_E_NO_REVOCATION_CHECK only with CERT_CHAIN_REVOCATION_CHECK_CHAIN.

Hi,

While running your changed tests on Windows, I think I found new failures.
Being a bot and all I'm not very good at pattern recognition, so I might be
wrong, but could you please double-check?
