RDMA/hns: Fix QP's resp incomplete assignment
[ Upstream commit d2e0ccffcdd7209fc9881c8970d2a7e28dcb43b9 ]
The resp passed to the user space represents the enable flag of qp,
incomplete assignment will cause some features of the user space to be
disabled.
Fixes: 90ae0b57e4a5 ("RDMA/hns: Combine enable flags of qp")
Fixes: aba457ca890c ("RDMA/hns: Support owner mode doorbell")
