Public bug reported:

When boot instance with dedicated cpu_policy, the cpu_pinning field of InstanceNUMATopology is '{}'.
But the function 'instance_topology_from_instance' just missed that fields when convert instance numa topology dict back to object:

https://github.com/openstack/nova/blob/master/nova/virt/hardware.py#L1150.

That leads to the cpu_pinning just ignored.
