This wrapper for sg_set_page() lets drivers add folios to a scatterlist
more easily. We could, perhaps, do better by using a different page
in the folio if offset is larger than UINT_MAX, but let's hope we get
a better data structure than this

This wrapper for sg_set_page() lets drivers add folios to a scatterlist
more easily. We could, perhaps, do better by using a different page
in the folio if offset is larger than UINT_MAX, but let's hope we get
a better data structure than this before we need to care about such
large folios.
