Don't parse PCI whitelist every time neutron ports are created
The neutronv2 API is calling the method get_pci_device_devspec()
everytime a neutron port is created in order to get a PciDeviceSpec for a given
PCI device. This method creates a new Whitelist (based on the config
CONF.pci_passthrough_whitelist) and parses it every time it is called. This
is not a huge overhead but this is obvioulsy not needed and a waste of cycles.
Since only neutronv2 API uses get_pci_device_devspec(), this commit removes
the method in favor of using the Whitelist object directly (like it is done
in the PciDevTracker).
