iomap: Add __iomap_put_folio helper

Browse source

Add an __iomap_put_folio() helper to encapsulate unlocking the folio,
calling ->page_done(), and putting the folio.  Use the new helper in
iomap_write_begin() and iomap_write_end().

This effectively doesn't change the way the code works, but prepares for
successive improvements.
