QUIC: disabled bidirectional SSL shutdown after 09fb2135a589. On QUIC connections, SSL_shutdown() is used to call the send_alert callback to send a CONNECTION_CLOSE frame. The reverse side is handled by other means. At least BoringSSL doesn't differentiate whether this is a QUIC SSL method, so waiting for the peer's close_notify alert should be explicitly disabled.
