mm/filemap: use filemap_end_dropbehind() for read invalidation
commit 25b065a744ff0c1099bb357be1c40030b5a14c07 upstream.
Use the filemap_end_dropbehind() helper rather than calling
folio_unmap_invalidate() directly, as we need to check if the folio has
been redirtied or marked for writeback once the folio lock has been
re-acquired.
