vti6: Use vti6_dev_init as the ndo_init function.
vti6_dev_init() sets the dev->iflink via a call to vti6_link_config(). After that, register_netdevice() sets dev->iflink = -1. So we loose the iflink configuration for vti6 tunnels. Fix this by using vti6_dev_init() as the ndo_init function. Then vti6_dev_init() is called after dev->iflink is set to -1 from register_netdevice().
