This reverts commit 6ae23ad36253a8033c5714c52b691b84456487c5.

The code has been in kernel since 4.4 but there are no in tree
code that uses. Unused code is broken code, remove it.

Tom if you have any real plans to develop on this work at all in
the immediate future, please speak up now.

Otherwise I'm applying Stephen's patch.

Thanks.

Oops, nope, I tell a lie. We used it initially and then realised we 
didn't strictly
need it since we only advertise IP_CSUM and IPV6_CSUM of inner
packets, so we should never be presented with a packet we'd need to
call the helper for. So we're not using it after all.
