When TLS handshake does not contain SNI extension would be able to close connection by nginx.

This situation may resolve server identification by address and IP dial directly attack.

See #195 for a feature request about rejecting SSL handshakes based on server name matching, and see this comment on how to do it in current nginx versions. Closing this as a duplicate of #195.
