An RPC-over-RDMA message may move a whole RPC Call or Reply using an RDMA Read
or Write. In this case the RPC message itself is not forwarded to any
subdissectors, and appears as an RPCoRDMA protocol frame of type RDMA_NOMSG.
The RPC-over-RDMA dissector should use the chunk lists in that frame to find
the associated RDMA Read or Write requests and re-assemble them into a full RPC
message, then pass that on to an appropriate subdissector.
