[I] [RDMA] 启用RDMA后client侧解析响应失败 (brpc)

[via GitHub]

SimonCqk opened a new issue, #2814:
URL: https://github.com/apache/brpc/issues/2814

   **Describe the bug (描述bug)**
   
   应用场景可以简化为client发起rpc请求，server收到请求后取回数据，并通过response attachment返回，追踪日志看：
   1. fuse->rpc->worker 完成
   2. worker收到响应->take data-> append to attachment完成
   3. fuse侧hang住，直到报错
   
   
   ```

参考https://github.com/apache/brpc/issues/2265对brpc收发方向的消息都打了日志，可见主要是正常的消息的和server所在进程，send方向的空数据：

   worker响应的代码很简单，blockletBuffer打印出之后确实是有数据的，没有进一步的排查头绪了。
   
   ```cpp
   _cntl->response_attachment().append(blockletBuffer->data(),  
blockletBuffer->size());
   ```
