mm: migrate: remove unused argument vma from migrate_misplaced_folio()

Commit ee86814b0562 ("mm/migrate: move NUMA hinting fault folio isolation
+ checks under PTL") removed the code that had used the vma argument in
migrate_misplaced_folio.

Since the vma argument was no longer used in migrate_misplaced_folio, this
patch removes it.
