    libvirt: report pci Type-PF type even when VFs are disabled

    libvirt < 1.3 reports virt_functions capability only when pf has
    VFs enabled. This workaround patch updates the is_physical_function
    function to read the sriov_totalvfs if exists and check it is
    greater than 0. The sriov_totalvfs is the number for the
    maximum possible VF for this PF. _get_pcidev_info in libvirt driver
    is updated to get the correct pci device type using this function.
