ipv4: ip_tunnel: spread netdev_lockdep_set_classes()
Inspired by yet another syzbot report.
IPv6 tunnels call netdev_lockdep_set_classes() for each tunnel type,
while IPv4 currently centralizes netdev_lockdep_set_classes() call from
ip_tunnel_init().
Make ip_tunnel_init() a macro, so that we have different lockdep
classes per tunnel type.
Fixes: 0bef512012b1 ("net: add netdev_lockdep_set_classes() to virtual drivers")
