    tun/tap: Use make_only_dev() for the autoclone device
    
    It's recommended and more correct to use make_only_dev() for the
    autoclone device, because the later open action will call
    devfs_spec_open() to create the device node in '/dev'.  See also the
    make_autoclone_dev(9) man page.
    
    Because the device created by make_only_dev() doesn't appear in '/dev',
    devfs_find_device_by_name() cannot find it.  Therefore, we need to pass
    the cdev_t returned by make_only_dev() to if_clone_create() so that the
    {tun,tap}_clone_create() can get the device to create the tun/tap
    interface.
