[Qemu-devel] [PULL 03/15] migration/rdma: Pass qemu_file errors across link

[Juan Quintela <quintela@redhat.com>]

From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>

If we fail for some reason (e.g. a mismatched RAMBlock)
and it's set the qemu_file error flag, pass that error back to the
peer so it can clean up rather than waiting for some higher level
progress.
