Title:
  updating incorrect resource during migration

Status in OpenStack Compute (nova):
  Expired

Bug description:
  In revert-resize method, migration.status changed to "reverted" in func revert_resize on dest node, and instance's host will be set in finish_revert_resize on source node.
  If an update available resource called during this time in source node, the resource of vm will free in source node too (include mem, cpu and pci).
  I think migration.status should be set only after instance's host changed.

  In resize-confirm method, resource is freed in function drop_move_claim. But if the vm migrate in 1 min, the uuid might recored in tracked_instances but not tracked_migrations.
  drop_move_claim should consider this situation.
