Clean up (for several purposes): - The MR's cid is initialized sooner so that tracepoints can show something reasonable even if the MR is never posted. - The MR's res.id doesn't change so the cid won't change either. Initializing the cid once is sufficient. - struct rpcrdma_frwr is going away soon.
