[IPV4]: Fix null dereference in ip_defrag
Been seeing occasional panics in my testing of 2.6.25-rc in ip_defrag.
Offending line in ip_defrag is here:
net = skb->dev->nd_net
where dev is NULL. Bisected the problem down to commit
ac18e7509e7df327e30d6e073a787d922eaf211d ([NETNS][FRAGS]: Make the
inet_frag_queue lookup work in namespaces).
Below patch (idea from Patrick McHardy) fixes the problem for me.
