Code Issues Proposed changes

Do not live migrate instance with non-NIC PCI device 

Nova does not support live migration for an instance with a
non-NIC PCI device. Updating the VIM to avoid triggering live
migrations for these instances - the pci_passthrough:alias
extra spec indicates that there is a non-NIC PCI device.
