Subject: [PATCH for-next 1/3] RDMA/rtrs: Remove duplicate cq_num assignment

line 1701 and 1713 are duplicate:
> 1701         cq_num = max_send_wr + max_recv_wr;
 1702         /* alloc iu to recv new rkey reply when server reports flags set */
 1703         if (clt_path->flags & RTRS_MSG_NEW_RKEY_F || con->c.cid == 0) {
 1704                 con->rsp_ius = rtrs_iu_alloc(cq_num, sizeof(*rsp),
 1705                                               GFP_KERNEL,
 1706                                               clt_path->s.dev->ib_dev,
 1707                                               DMA_FROM_DEVICE,
 1708                                               rtrs_clt_rdma_done);
 1709                 if (!con->rsp_ius)
 1710                         return -ENOMEM;
 1711                 con->queue_num = cq_num;
 1712         }
> 1713         cq_num = max_send_wr + max_recv_wr;
