Mel Gorman d34c5fa06f mm: page_alloc: only check the zone id check if pages are buddies 
A node/zone index is used to check if pages are compatible for merging
but this happens unconditionally even if the buddy page is not free. Defer
the calculation as long as possible. Ideally we would check the zone boundary
but nodes can overlap.
