Subject: RDMA/hns: Assign zero for pkey_index of wc in hip08
Patch-mainline: v4.16-rc1
Git-commit: 6c1f08b347f64de38460d5b3d1eb4a30028869cb
References: bsc#1104427 FATE#326416

Because pkey is fixed for hip08 RoCE, it needs to assign zero for
pkey_index of wc. otherwise, it will happen an error when establishing
connection by communication management mechanism.
