[SRU][N:gke][PATCH 008/106] mm/pgtable: make pte_next_pfn() independent of set_ptes()

Let's provide pte_next_pfn(), independently of set_ptes().  This allows
for using the generic pte_next_pfn() version in some arch-specific
set_ptes() implementations, and prepares for reusing pte_next_pfn() in
other context.
