[PATCH net] net: batman-adv: Fix possible memleaks when fail to register_netdevice

[gfree . wind]

From: Gao Feng <f...@ikuai8.com>

Because the func batadv_softif_init_late allocate some resources and
it would be invoked in register_netdevice. So we need to invoke the
func batadv_softif_free instead of free_netdev to cleanup when fail
to register_netdevice.
