Hongfu Li a44ab4bd1e ksm: update comments and docs to reference folio->mapping ...

The KSM code already stores and checks the stable node key via
folio->mapping, but the comment in ksm_get_folio() and the reverse mapping
documentation in ksm.rst still refer to page->mapping.

This is a pure wording update to match the folio-based implementation.  No
functional change is intended.
