charset="utf-8" When qemu_rdma_wait_comp_channel() receives an event from the completion channel, it reports an error "receive cm event while wait comp channel,cm event is T", where T is the numeric event type. However, the function fails only when T is a disconnect or device removal. Events other than these two are not actually an error, and reporting them as an error is wrong. If we need to report them to the user, we should use something else, and what to use depends on why we need to report them to the user. For now, report this error only when the function actually fails.
