ipv4: additional update of dev_net(dev) to struct *net in ip_fragment.c, NULL ptr OOPS
ipv4 ip_frag_reasm(), fully replace 'dev_net(dev)' with 'net', defined
previously patched into 2.6.29.
Between 2.6.28.10 and 2.6.29, net/ipv4/ip_fragment.c was patched,
changing from dev_net(dev) to container_of(...). Unfortunately the goto
section (out_fail) on oversized packets inside ip_frag_reasm() didn't
get touched up as well. Oversized IP packets cause a NULL pointer
dereference and immediate hang.
I discovered this running openvasd and my previous email on this is
titled: NULL pointer dereference at 2.6.32-rc8:net/ipv4/ip_fragment.c:566
