Phil Oester 12b101555f [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
ac18e7509e ([NETNS][FRAGS]: Make the
inet_frag_queue lookup work in namespaces).  

Below patch (idea from Patrick McHardy) fixes the problem for me.
