Subject: [PATCH] migration/rdma: zore out head.repeat to make the error more
 clear

cheery-pick from 2ada4b63f1764d13a2b9ca9cbeb5feda46ab6851

Previously, we got a confusion error that complains
the RDMAControlHeader.repeat:
qemu-system-x86_64: rdma: Too many requests in this message (3638950032).Bailing.

Actually, it's caused by an unexpected RDMAControlHeader.type.
After this patch, error will become:
qemu-system-x86_64: Unknown control message QEMU FILE
