This bug was revealed on backend side by reg-tests/ssl/del_ssl_crt-list.vtc when run wich QUIC connections. As expected by the test, a TLS alert is generated on servsr side. This latter sands a CONNECTION_CLOSE frame with a CRYPTO error (>= 0x100). In this case the client closes its QUIC connection. But the stream connection was not informed. This leads the connection to be closed after the server timeout expiration. It shouls be closed asap. This is the reason why reg-tests/ssl/del_ssl_crt-list.vtc could succeeds or failed, but only after a 5 seconds delay. To fix this, mimic the ssl_sock_io_cb() for TCP/SSL connections. Call the same code this patch implements with ssl_sock_handle_hs_error() to correctly handle the handshake errors. Note that some SSL counters were not incremented for both the backends and frontends. After such errors, ssl_sock_io_cb() start the mux after the connection has been flagged in error. This has as side effect to close the stream in conn_create_mux(). Must be backported to 3.3 only for backends. This is not sure at this time if this bug may impact the frontends.
