[PULL 05/11] migration/rdma: zore out head.repeat to make the error more clear

[Juan Quintela]

From: Li Zhijian <lizhijian@fujitsu.com>

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
