The newly added callback pointers cause a warning for some configurations:

In file included from net/ipv6/af_inet6.c:45:0:
include/linux/netfilter_ipv6.h:38:51: error: 'struct nf_queue_entry' declared inside parameter list will not be visible outside of this definition or declaration [-Werror]

Adding a forward declaration for the type avoids the warnings.

Fixes: 9faa679ee7ec ("netfilter: move reroute indirection to struct nf_ipv6_ops")
