mm, vmstat: skip reporting offline pages in pagetypeinfo
pagetypeinfo_showblockcount_print skips over invalid pfns but it would
report pages which are offline because those have a valid pfn. Their
migrate type is misleading at best.
Now that we have pfn_to_online_page() we can use it instead of
pfn_valid() and fix this.
