Eric Dumazet a1b995a2f5 ipv4: raw: fix icmp_filter()
[ Upstream commit ab43ed8b74 ]

icmp_filter() should not modify its input, or else its caller
would need to recompute ip_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.
