Title:
  Errors in finish_revert_resize can leave migration.dest_compute
  pointing at source_compute

Status in OpenStack Compute (nova):
  Fix Released
Status in OpenStack Compute (nova) rocky series:

Bug description:
  Because of this code in finish_revert_resize:

  https://github.com/openstack/nova/blob/8cdb8cc7c56b574382b9a9fff662cc95e78136a2/nova/compute/manager.py#L4121

  And the @errors_out_migration decorator on the method, if something
  fails after that line we will save the migration object changes which
  would leave the dest_compute pointing at the source_compute, which
  could be very confusing when trying to debug.

  The comment says the field is set temporarily but it's not really
  temporary if the migration changes are saved like in that decorator.
