Subject: [PATCH v3 08/15] 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.
