RDMA/hns: Fix the wrong value of rnr_retry when querying qp
[ Upstream commit 99fcf82521d91468ee6115a3c253aa032dc63cbc ]
The rnr_retry returned to the user is not correct, it should be got from
another fields in QPC.
Fixes: bfe860351e31 ("RDMA/hns: Fix cast from or to restricted __le32 for driver")
