Public bug reported:
In method pre_live_migration, we create instance's directory at destination
host during block live migration.
If some exceptions happen before creating domain succesfully like failure of
connecting volume to destination host,
then we can't destroy instance in method rollback_live_migration_at_destination.
In this case we don't remove the instance's directory, this will lead
anDestinationDiskExists when live migratin same instance to same destination.
