Public bug reported:

When we resize (change the flavor) of an instance that has a NUMA
topology defined, the NUMA info from the new flavor will not be
considered during scheduling. The instance will get re-scheduled based
on the old NUMA information, but the claiming on the host will use the
new flavor data. Once the instane sucessfully lands on a host, we will
still use the old data when provisioning it on the new host.

We should be considering only the new flavor information in resizes.
