mm: page_alloc: consolidate free page accounting
Free page accounting currently happens a bit too high up the call stack,
where it has to deal with guard pages, compaction capturing, block
stealing and even page isolation. This is subtle and fragile, and makes
it difficult to hack on the code.
Now that type violations on the freelists have been fixed, push the
accounting down to where pages enter and leave the freelist.
