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: aba457ca890c ("RDMA/hns: Support owner mode doorbell")
