Wrong OpenSSL validation result for the unable_to_get_crl case

[zacikpa]

OpenSSL does not return any error message for the unable_to_get_crl example chain.
It should return X509_­V_­ERR_­UNABLE_­TO_­GET_­CRL.

Possible culprit might be the load_cert_crl_http function in validation/client/openssl/client.c. Its return value might not be processed properly.

Nice catch, may be a possible bug in the library. Worth investigating.
