[XFRM] IPv6: Fix dst/routing check at transformation.
IPv6 specific thing is wrongly removed from transformation at net-2.6.25. This patch recovers it with current design. o Update "path" of xfrm_dst since IPv6 transformation should care about routing changes. It is required by MIPv6 and off-link destined IPsec. o Rename nfheader_len which is for non-fragment transformation used by MIPv6 to rt6i_nfheader_len as IPv6 name space.
