commit 1faba27f11c8da244e793546a1b35a9b1da8208e upstream.

The W=1 compilation of allmodconfig generates the following warning:

net/ipv6/icmp.c:448:6: warning: no previous prototype for 'icmp6_send' [-Wmissing-prototypes]
  448 | void icmp6_send(struct sk_buff *skb, u8 type, u8 code, __u32 info,
      |      ^~~~~~~~~~

Fix it by providing function declaration for builds with ipv6 as a module.
