Bug description:
  1、in /nova/compute/manager.py  pre_live_migration function , the table of block_device_mapping has been updated the destination host's target LUN id .
  2、in /nova/compute/manager.py  post_live_migration_at_destination function ,when  cleanup source host's  target LUN , first     query  target LUN id from table of  block_device_mapping, but at the above step , the  target LUN id has been updated as  the destination host's target LUN id. so ,when the source and the destination  target LUN id are not same , error will occur.
