[NET]: Reorder fields of struct dst_entry

This last patch (but not least :) ) finally moves the next pointer at
the end of struct dst_entry. This permits to perform route cache
lookups with a minimal cost of one cache line per entry, instead of
two.

Both 32bits and 64bits platforms benefit from this new layout.
