fix: Duplicate close net.Listener

[mygityf]

http/server.go:
line: 3016
net.Listener is close in func http.Server.Serve() by default.

// Some code piece of http.Server.Serve()

func (srv *Server) Serve(l net.Listener) error {
	if fn := testHookServerServe; fn != nil {
		fn(srv, l) // call hook with unwrapped listener
	}

	origListener := l
	l = &onceCloseListener{Listener: l}
	// HERE: listener is close by default
	defer l.Close()
