QUIC: set NGX_TCP_NODELAY_DISABLED for fake stream connections. Notably, it is to avoid setting the TCP_NODELAY flag for QUIC streams in ngx_http_upstream_send_response(). It is an invalid operation on inherently SOCK_DGRAM sockets, which leads to QUIC connection close. The change reduces diff to the default branch in stream content phase.
