batman-adv: use unregister_netdevice() when softif_create fails 

When entering softif_create(), the rtnl lock has already been acquired
by store_mesh_iface().
(store_mesh_iface() -> hardif_enable_interface() -> softif_create)

In case of an error, we should therefore call unregister_netdevice()
instead of unregister_netdev().

unregister_netdev() tries to acquire the rtnl lock itself and deadlocks
in this situation. unregister_netdevice() assumes that the rtnl lock
is already been held.
