The ksm only contains single pages, so we could add a new func
ksm_get_folio for get_ksm_page to use folio instead of pages to save a
couple of compound_head calls.
After all caller replaced, get_ksm_page will be removed.

Just realized that you should adjust the function name in the comment
above this function in this patch.
