Subject: RDMA/hns: Assign the correct value for tx_cqn
Patch-mainline: v4.16-rc1
Git-commit: 6d13b869ea1e929842e9d758867e4b7473759f9d
References: bsc#1104427 FATE#326416
When modifying qp from init to init, it need to assign the cqn of send cq
for tx cqn field of qp context. Otherwise, it will cause a mistake when
the send and recv cq sizes are different.
