Title:
  Instance without "extra" data crashes nova-compute

Status in OpenStack Compute (nova):
  Fix Released
Status in OpenStack Compute (nova) kilo series:
  Fix Released

Bug description:
  I'm upgrading from Icehouse to Kilo. I have a single instance that was
  created in Icehouse. After the upgrade, nova-compute crashes because
  it's looking for instance "extra" data that is not there.

  To fix this, we need to check if there is any "extra" data for the
  instance before trying to read properties such as "numa_topology".
