Public bug reported:
Reproduction Steps:
Nova: 29.2.1.dev18
Placement: 11.0.0.rc2.dev2
1. Enable the PCI in Placement feature.
2. Create a VM with a single GPU device and verify normal operation. The output
displays as follows:

3. Perform migration.
nova migrate 61cef01f-7770-4743-ac97-229d0d9a9430 --host gpu1-70-47
Expected Result:
The VM should acquire one PCI hostdev, with a single allocation recorded in
both the Nova database and Placement.
Actual Result:
The VM acquires one hostdev, and the Nova database shows one allocation, but
two allocations are recorded in Placement.
