Description

When zombied instances appear(You can also see bug https://bugs.launchpad.net/nova/+bug/911366),
set running_deleted_instance_poll_interval = 60 and running_deleted_instance_action = reap, then nova-compute service will clear those zombied instances, but if those instances is boot from volume or had volumes attached. After clear, zombied instances cleared, but volumes with attached status exist, and if those volumes are bootable and used to boot volume and set deleted_on_termination=True, thoses volume will still exist and in attached status but instance did not exist.

Steps to reproduce

1. set running_deleted_instance_poll_interval=60 and running_deleted_instance_action = reap.
2. update an running instance status to deleted.
3. restart nova-compute service and wait 60 seconds.

Expected result

Previous test bootable volume was deleted and volumes attached to
zombied instances ware detached.

Actual result

Previous test bootable volume was in state attached and in-use, volumes
attached to zombied instances ware in-use and attached to those zombied
instances.
