This patch renames the zone LRU stats as printed in /proc/vmstat to avoid
confusion. This keeps both the node and zone stats which normally will be
redundant but should always be roughly in sync.
This is a fix to the mmotm patch mm-add-per-zone-lru-list-stat.patch

Actually, I don't have any number to prove how much keeping the stat
both zone and node increases performance but I don't object it.
