At start up of nova-compute service, the PCI stat pools are
populated based on information in pci_devices table in Nova
database. The pools are updated only when new device is added
or removed but not on any device changes like device type.
If an existing device is configured as SRIOV and nova-compute
is restarted, the pci_devices table gets updated but the device
is still listed under the old pool in pci_tracker.stats.pool
(in-memory object).
This patch looks for device type updates in existing devices
and updates the pools accordingly.

The functional test requires to skip the capabilities of pci
device. This can be done by getting capability template out of
pci_dev_template [1] which is introduced by commit
b927748c25. Not able to clean
backport the mentioned commit and so removed funtional test
case.
