svcrdma: Update the synopsis of svc_rdma_read_data_item()
Since the RDMA Read I/O state is now contained in the recv_ctxt, svc_rdma_build_read_data_item() can use that recv_ctxt to derive that information rather than the other way around. This removes another usage of the ri_readctxt field, enabling its removal in a subsequent patch. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
