ipv6 fib: Make rt6_info{} more cache-line aware.
The head element of rt6_info{} is dst_entry{}, and
IPv6 specific elements follow.
Because elements at the end of dst_entry{} are frequently
updated, it is not good to put frequently-used static
elements, such as rt6i_idev, rt6i_dst or rt6i_flags in the
same cache line.
On the other hand, fib6_table, rt6i_node or rt6i_gateway are
rarely used, so it is okay to stay in the same cache line.
Let's rearrange rt6_info{}.
