net: raw: revert unrelated change
Commit5640f76858
("net: use a per task frag allocator") accidentally contained an unrelated change to net/ipv4/raw.c, later committed (without the pr_err() debugging bits) in net tree as commitab43ed8b74
(ipv4: raw: fix icmp_filter()) This patch reverts this glitch, noticed by Stephen Rothwell. Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
