client connection has been closed by peer

Describe the bug 仅使用 netpoll client 进行建连，当 server 设置 ReadTimeout 比较小时，例如这样：

// server
func main() {
    s := http.Server{
        ReadTimeout: time.Millisecond,
    }

    ln, err := net.Listen("tcp", ":8000")
    if err != nil {
        panic(err)
    }
    s.Serve(ln)
}

// client
dialer := netpoll.NewDialer()
conn, err := dialer.DialTimeout("tcp", "127.0.0.1:8000", 2*time.Second)

client 压力大，调度慢时出现 client connection has been closed by peer 报错，原生 net 则不会
