    Lookup nic feature by PCI address

    In some environments the libvirt nodedev list can become out of sync
    with the current MAC address assigned to a netdev, As a result the
    nodedev lookup can fail. This results in an uncaught libvirt exception
    which breaks the update_available_resource function resultingin an
    incorrect resource view in the database.

    e.g. libvirt.libvirtError: Node device not found:
    no node device with matching name 'net_enp7s0f3v1_ea_60_77_1f_21_50'

    This change removes the dependency on the nodedev name when looking up
    nic feature flags.
