RPC超时后 空指针异常

RPC超时后 空指针异常

1. kitex：github.com/cloudwego/kitex v0.5.2
2. netpool: github.com/cloudwego/netpoll v0.3.2

重现重现行为的步骤：

1. kitex 调用 kitex 的RPC接口设置超时
2. 在RPC超时后 提供服务的方法还在执行
3. 在提供服务的方法执行完后出现错误
4. 后续网络操作变的非常缓慢，比如websocket发送文本，花费了大约80秒

预期

1. 无错误，继续执行后续操作

去掉kitex的多路复用就可以了，server.WithMuxTransport() 。。。。。。。。。。。。。。。

[joway]

@voyager-hang server 开启多路复用的时候，client 也必须要使用多路复用
