svcrdma: Update the synopsis of svc_rdma_read_call_chunk()

Since the RDMA Read I/O state is now contained in the recv_ctxt,
svc_rdma_read_call_chunk() can use that recv_ctxt to derive the
read_info rather than the other way around. This removes another
usage of the ri_readctxt field, enabling its removal in a
subsequent patch.
