Public bug reported:
After upgrade from xenial/ocata to bionic/queens SR-IOV instance
creation (--vnic-type direct) fails with missing devices:
The pci_devices mysql table if filled with wrong PCI entries, that do
not exist on the server. Restarting nova-compute and nova-cloud-
controller services did not fix (rediscover) the proper PCI devices.
