[PULL,12/65] migration/rdma: Consistently use uint64_t for work request IDs

Commit Message

From: Markus Armbruster <[e-mail]>

We use int instead of uint64_t in a few places.  Change them to
uint64_t.

This cleans up a comparison of signed qemu_rdma_block_for_wrid()
parameter @wrid_requested with unsigned @wr_id.  Harmless, because the
actual arguments are non-negative enumeration constants.
