ext4: move the calculation of wbc->nr_to_write to mpage_folio_done()
mpage_folio_done() should be a more appropriate place than
mpage_submit_folio() for updating the wbc->nr_to_write after we have
submitted a fully mapped folio. Preparing to make mpage_submit_folio()
allows to submit partially mapped folio that is still under processing.
