possible resource leak of ibv_comp_channel in rdma

我在阅读rdma部分代码时，在 `GlobalRdmaInitializeOrDieImpl` 函数中看到一行比较奇怪的代码。它在全局初始化的过程中调用了 `IbvCreateCompChannel` 来创建应该由 `RdmaEndpoint` 管理的资源，并且没有对创建的 `ibv_comp_channel` 进行销毁。

请问这行代码符合预期吗？如果符合预期，请问这一行的作用是什么呢?

代码位置 https://github.com/apache/brpc/blob/d7eca3991f0f38121a4e40831e548d8802fa6b1a/src/brpc/rdma/rdma_helper.cpp#L492

Start in src/brpc/rdma/rdma_helper.cpp at GlobalRdmaInitializeOrDieImpl and the IbvCreateCompChannel call linked in the issue. Trace how the resulting ibv_comp_channel is owned and whether RdmaEndpoint provides its lifecycle management. Done means establishing whether the allocation is intentional and, if not, identifying the required cleanup path.
