    Skip checking of target_dev for vhostuser

    Nova skips detaching of ovs dpdk interfaces
    thinking that it's already detached because
    get_interface_by_cfg() return no inteface.
    This is due to _set_config_VIFVHostUser()
    not setting target_dev in configuration while
    LibvirtConfigGuestInterface sets target_dev
    if tag "target" is found in the interface.

    As target_dev is not a valid value for
    vhostuser interface, it will not be checked
    for vhostuser type.
