    Fix incorrect cellid numbering for NUMA memnode
    
    cellid should contain node index, but it actually has the cell nodeset.
    For the given node topology cells: 0 1 16 17
    Wrong cellid:
        <memnode cellid='0' mode='strict' nodeset='0'/>
        <memnode cellid='1' mode='strict' nodeset='1'/>
        <memnode cellid='16' mode='strict' nodeset='16'/>
        <memnode cellid='17' mode='strict' nodeset='17'/>
    Correct cellid:
        <memnode cellid='0' mode='strict' nodeset='0'/>
        <memnode cellid='1' mode='strict' nodeset='1'/>
        <memnode cellid='2' mode='strict' nodeset='16'/>
        <memnode cellid='3' mode='strict' nodeset='17'/>

Title:
  Incorrect cellid in NUMA memnode

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  Description
  ===========

  Nova generating wrong cellid for numa memnode.

  Some systems number nodeset for the NUMA topology in non-sequential
  way, as follows:

  node   0   1  16  17



  Steps to reproduce
  ==================
  Create a flavor w/ hw:numa_nodes=4 (hw:cpu_policy unset)

  Spawn an instance across multiple nodes

  Check nodeset in the instance XML


  Expected result
  ===============

  Correct cellid:

      <memnode cellid='0' mode='strict' nodeset='0'/>

      <memnode cellid='1' mode='strict' nodeset='1'/>

      <memnode cellid='2' mode='strict' nodeset='16'/>

      <memnode cellid='3' mode='strict' nodeset='17'/>


  
  Actual result
  =============

  
  Wrong cellid:

      <memnode cellid='0' mode='strict' nodeset='0'/>

      <memnode cellid='1' mode='strict' nodeset='1'/>

      <memnode cellid='16' mode='strict' nodeset='16'/>

      <memnode cellid='17' mode='strict' nodeset='17'/>


  Environment
  ===========

  Ubuntu Xenial 16.10, OpenStack Mitaka release, Libvirt 1.3.1

  Note: This issue has been found / tested on Ubuntu KVM on Power
  (ppc64le arch), however, it *may* affect other architectures.
