mm/huge_memory: add page->private check back in __split_folio_to_order()
bebabf5 
page->private should not be set in tail pages. Commit 4265d67
("mm/migrate_device: add THP splitting during migration") removed it
without a proper reason. Add it back.

mm/page_alloc: check page->private upon page free
1b4151f 
Any user is supposed to zero their allocated page->private at free time,
including both head and tail pages if the freed page is compound. Add
VM_WARN_ON_ONCE to check page->private.

Whoever encountering warnings from this commit needs to fix code that
does not zero ->private when freeing a page/folio.
