Title:
  instance's directory is not removed  at destination host during
  rollback of pre_live_migration

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  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.
