Hook into iomap_invalidate_folio() so that if the entire folio is being invalidated during truncation, the dirty state is cleared and the folio doesn't get written back. As well the folio's corresponding ifs struct will get freed. Hook into iomap_is_partially_uptodate() since iomap tracks uptodateness granularly when it does buffered writes.
