The commit c1ccc1a316 introduced
a regression when NUMA live migration was done on shared storage
The live migration support for the power mgmt feature means we need to
call driver.cleanup() for all NUMA instances to potentially offline
pcpus that are not used any more after the instance is migrated away.
However this change exposed an issue with the disk cleanup logic. Nova
should never delete the instance directory if that directory is on
shared storage (e.g. the nova instances path is backed by NFS).
This patch will fix that behavior so live migration will function
