RDMA/hns: Fix retry_cnt and rnr_cnt when querying QP

The maximum number of retransmission should be returned when querying QP,
not the value of retransmission counter.

Fixes: 99fcf825 ("RDMA/hns: Fix the wrong value of rnr_retry when querying qp")
Fixes: 926a01dc ("RDMA/hns: Add QP operations support for hip08 SoC")
