break out numa_maps gather_pte_stats() checks
commit 3200a8aaab0c9ccdc0f59b0dac2d4a47029137fa upstream.
gather_pte_stats() does a number of checks on a target page
to see whether it should even be considered for statistics.
This breaks that code out in to a separate function so that
we can use it in the transparent hugepage case in the next
patch.
