Willem de Bruijn fe63339ef3 ip6_gre: Revert "ip6_gre: add validation for csum_start" 
This reverts commit 9cf448c200ba9935baa94e7a0964598ce947db9d.

This commit was added for equivalence with a similar fix to ip_gre.
That fix proved to have a bug. Upon closer inspection, ip6_gre is not
susceptible to the original bug.

So revert the unnecessary extra check.

In short, ipgre_xmit calls skb_pull to remove ipv4 headers previously
inserted by dev_hard_header. ip6gre_tunnel_xmit does not.
