mm/ksm: convert chain series funcs and replace get_ksm_page

In ksm stable tree all page are single, let's convert them to use and
folios as well as stable_tree_insert/stable_tree_search funcs.  And
replace get_ksm_page() by ksm_get_folio() since there is no more needs.

It could save a few compound_head calls.
