Title:
  nova evacuate of instances with sriov ports fails due to use of source
  device

Bug description:
  When nova evacuate or host-evacuate are used to recreate instances
  with sriov ports the instances are allocated new device ids on the
  target and neutron is updated accordingly.  However the network info
  data passed to the driver spawn method is not updated and thus the
  instance tries to use the device id they were allocated on the source
  node.  If a pre existing instance is using that device id or no such
  device exists on the target node then the instance will fail to start.
