net: raw: revert unrelated change

Browse Source 
Commit 5640f76858 ("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 commit ab43ed8b74 (ipv4: raw: fix icmp_filter())

This patch reverts this glitch, noticed by Stephen Rothwell.
