Adam Litke 6d0ee85040 balloon: Do not save VM state wrt asynchronous virtio operations 
When working with the VM state (for loadvm/savevm and migration), it is not
valid to load and store pointers since the validity of those pointers cannot be
assured in the new qemu address space.  Therefore, virtio_balloon_save() and
virtio_balloon_load() must not handle the stats-related fields in struct
VirtIOBalloon.

If a memory stats request is in-flight at the time of a migration or savevm,
the request will not complete and should be resubmitted once migration or
loadvm completes.  Note that this extremely small race window can only be
triggered using QMP so it is not possible to hang the user monitor.
