Public bug reported:


Description
===========
After evacuate an instance to a new host, then live-migration it to the old host, nova-compute report "DestinationDiskExists" error.

When nova-compute on old host restarts, it only deletes the evacuated
instance path that needs destroying disks. If the instance is on shared
block storage such as ceph, nova-compute will not delete instance path.

Steps to reproduce
===========
* create an instance on a compute node using ceph backend
* crash the compute node
* evacuate the instance
* reboot the crashed node

Expected result
===============
The evacuated instance path should be deleted.

Actual result
=============
After crashed nova-compute restarts, the instance path  still exists.

Environment
===========
I used stable Kilo. But I think it's still valid on the master.
