RDMA/hns: Dump whole QP/CQ/MR resource in raw
Currently, some fields in the QP/CQ/MR resource can be dumped by rdma-tool, but this information is not enough. It is very inconvenient to continue to expand on the current field, and it will also introduce some trouble to parse these raw data. This patch dump whole resource in raw to avoid the above problems.
