[PATCH 055/100] ip: use ip_hdr() in __ip_make_skb() to retrieve IP header

[Luis Henriques]

3.5.7.23 -stable review patch.  If anyone has any objections, please let me know.

From: Ansis Atteka <aatteka at nicira.com>

commit 749154aa56b57652a282cbde57a57abc278d1205 upstream.

skb->data already points to IP header, but for the sake of
consistency we can also use ip_hdr() to retrieve it.
