Subject: RDMA/hns: return 0 rather than return a garbage status value
Patch-mainline: v4.15-rc1
Git-commit: 63ea641f496ffe08b7d81589a1e1e1c43a6af9bd
References: bsc#1104427 FATE#326416
For the case where hr_qp->state == IB_QPS_RESET, an uninitialized
value in ret is being returned by function hns_roce_v2_query_qp.
Fix this by setting ret to 0 for this specific return condition.
