This series fixes three RDMA migration issues.

v1->v2:
  - patch1/2: Collect Reviewed-by
  - patch2: Add reproducation step and error logs in commit message
  - patch3: Wrap the post-send op and retry logic into a helper, and
            retry only once after draining a completion when the queue
            is full. (I believe ENOMEM is only recoverable in the
            queue-full case, so we retry once; it should succeed after
            a completion is drained. Any further ENOMEM is treated as
            non-recoverable.)

Yanfei Xu (3):
  migration/rdma: Fix write-side shutdown
  migration/rdma: Post initial receive before accepting
  migration/rdma: Retry control sends on full queue
