mm: migrate_device: convert to migrate_device_coherent_folio()

Patch series "mm: finish isolate/putback_lru_page()".

Convert to use more folios in migrate_device.c, then we could remove
isolate_lru_page() and putback_lru_page().  


This patch (of 6):

Save a few calls to compound_head() and use folio throughout.
