[PATCH V2 for-next 6/6] RDMA/hns: Assign dest_qp when deregistering mr

It needs to create eight reserve QPs for resolving
a bug of hip06. When deregistering mr, it will issue
a rdma write for every reserve QPs.

In the above process, it needs to assign dest_qp.
Otherwise, it will trigger free mr work fail.
