Title:
  refresh attachment error when bdm.attachment_id lost

Status in OpenStack Compute (nova):
  Opinion

Bug description:
  Description
  ===========
  I cherry-picked the Xena patch for using in wallaby, https://blueprints.launchpad.net/nova/+spec/nova-manage-refresh-connection-info, and an unexpected error occurred.
  My OpenStack was wallaby upgraded from Newton, I needed to refresh volume_attachment of Newton version instances, since the bdm table field attachment_id was added in Pike, so I executed the command to the old instance in Wallaby got the error was that could not find the volume attachment by attachment id in bdm.

  Steps to reproduce
  ==================
  nova-manage refresh volume_attachment instance_id volume_id connector.json

  Expected result
  ===============
  Deleted and created volume attachment successfully.

  Actual result
  =============
  Actually recreated a new volume_attachment but the old one did not be deleted.

  Environment
  ===========
  Wallaby upgraded from Newton, hypervisor: Libvirt+KVM

  Logs & Configs
  ===========
  Select the database and see two ACTIVE volume attachment for the same instance exist:

  MariaDB [(none)]> use cinder
  Reading table information for completion of table and column names
  You can turn off this feature to get a quicker startup with -A
