crypt32: Properly check root certificate in CERT_CHAIN_REVOCATION_CHECK_CHAIN.

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.
