[IPV6]: Only set nfheader_len for top xfrm dst
We only need to set nfheader_len in the top xfrm dst. This is because
we only ever read the nfheader_len from the top xfrm dst.
It is also easier to count nfheader_len as part of header_len which
then lets us remove the ugly wrapper functions for incrementing and
decrementing header lengths in xfrm6_policy.c.
