Michael S. Tsirkin 6785011f8b ipv4: validate checksum_start before completing checksum 
If a packet with bad checksum metadata gets into the ipv4 stack,
skb_checksum_help can corrupt the network header and cause a bunch of
mischief.

This was discovered and reported by Paulos, and has been reporoduced
by others independently since.

We really shouldn't allow such packets in, but as a defence
in depth measure, let's also check before we complete the checksum.

A more complete validation at input is forthcoming, but needs more work.

Fixes: f43798c276 ("tun: Allow GSO using virtio_net_hdr")
Fixes: bfd5f4a3d6 ("packet: Add GSO/csum offload support.")
