HTTP/3: fixed OpenSSL compatibility layer initialization. SSL context is not present if the default server has neither certificates nor ssl_reject_handshake enabled.

Additionally, non-default servers with distinct SSL contexts need to initialize compatibility layer in order to complete a QUIC handshake.
