ngx_http_v3_init() is only called in ngx_http_init_connection, as ls->handler. And then ngx_quic_listen add the main quic connection to udp rbtree.
It call main quic connection read->handler If find connection in ngx_lookup_udp_connection, else call ls->handler.
But when ngx_http_v3_init() is called by _another_ connection that is a stream?
