ipv6: raw: fix icmpv6_filter()
[ Upstream commit 1b05c4b50edbddbdde715c4a7350629819f6655e ]
icmpv6_filter() should not modify its input, or else its caller
would need to recompute ipv6_hdr() if skb->head is reallocated.
Use skb_header_pointer() instead of pskb_may_pull() and
change the prototype to make clear both sk and skb are const.
Also, if icmpv6 header cannot be found, do not deliver the packet,
as we do in IPv4.
