Title:
  Don't allow to resize down the default ephemeral disk

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  If we create an instance with the default ephemeral disk and then to
  re-size it down, we get wrong ephemeral size.

      eph_size = (block_device.get_bdm_ephemeral_disk_size(ephemerals)

  It will return 0, if you don't create an ephemeral disk by the means
  of --block-device explicitly - nova will create a 'default' ephemeral
  disk for you, which won't be listed in block device mapping.
