ntfs: Correct mark_ntfs_record_dirty() folio conversion

ntfs: Correct mark_ntfs_record_dirty() folio conversion

We've already done the work of block_dirty_folio() here, leaving
only the work that needs to be done by filemap_dirty_folio().
This was a misconversion where I misread __set_page_dirty_nobuffers()
as __set_page_dirty_buffers().

Fixes: 1d36760b9728 ("fs: Convert __set_page_dirty_buffers to block_dirty_folio")
