mm: migrate: convert migrate_misplaced_page() to migrate_misplaced_folio()
At present, numa balance only support base page and PMD-mapped THP, but we
will expand to support to migrate large folio/pte-mapped THP in the
future, it is better to make migrate_misplaced_page() to take a folio
instead of a page, and rename it to migrate_misplaced_folio(), it is a
preparation, also this remove several compound_head() calls.
