These were left over from the last series (for 6.8).
The idea here is to post all work needed for sending one Reply with
just a single ib_post_send() -- the Send WR and all Write WRs are
chained together.
The purpose of that is to reduce the number of doorbells and
completions per RPC, which will hopefully improve transport
scalability.
