Fix failure of source volume deletion in migrate_volume_completion

In VolumeManager.migrate_volume_completion(), when volume_status is not
'retyping', status_update is not set. However, status_update is always
referenced as dictionary on volume deletion path, so it fails to delete
migration source volume. This patch fixes the issue.
