mm/khugepaged: convert collapse_pte_mapped_thp() to use folios
This removes 2 calls to compound_head() and helps convert khugepaged to
use folios throughout.
Previously, if the address passed to collapse_pte_mapped_thp()
corresponded to a tail page, the scan would fail immediately. Using
filemap_lock_folio() we get the corresponding folio back and try to
operate on the folio instead.
