RDMA/hns: Assign dest_qp when deregistering mr

BugLink: http://bugs.launchpad.net/bugs/1756097
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.

When modify qp from init to rtr, it needs to set
the value of dest_qp_num. Otherwise, it will lead
an error of freeing mr.
