svcrdma: Update synopsis of svc_rdma_send_reply_chunk()
Preparing for subsequent patches, no behavior change expected. Pass the RPC Call's svc_rdma_recv_ctxt deeper into the sendto() path. This enables passing more information about Requester- provided Write and Reply chunks into the lower-level send functions. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
