    Fix nova-hypervisor not showing up on nodes w/c62x QAT devices

    When nova is gathering pci info, it should not query pci net info
    for c62x QAT devices.

    This fix checks for the presence of pci_capability fields prior
    to accessing them.

    Also, c62x devices do not have a "net" subdir under
    /sys/bus/pci/devices/<pci address>/
    This fix prevents trying to access this subdir for c62x QAT devices,
    therefore stopping the flow of "No net device was found for VF"
    messages in nova compute logs.

    Ported from internal commit 28955dec983
