[PATCH v1 11/16] svcrdma: Update synopsis of svc_rdma_send_reply_msg()

[Chuck Lever <chuck.lever@oracle.com>]

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 those lower-level functions.
