openssl: RFC7250 handshakes with unauthenticated servers don't abort as expected

A flaw was found in OpenSSL's RFC7250 Raw Public Key RPK authentication. This vulnerability allows man-in-the-middle MITM attacks via failure to abort TLS/DTLS handshakes when the server's RPK does not match the expected key despite the SSLVERIFYPEER verification mode being set...
