If we're punching a hole in a large folio, we need to remove the
per-folio iomap data as the folio is about to be split and each page will
need its own. If a dirty folio is only partially-uptodate, the iomap
data contains the information about which blocks cannot be written back,
so assert that a dirty folio is fully uptodate.
