hugetlb: indicate surplus huge page counts in per-node meminfo
Currently we show the surplus hugetlb pool state in /proc/meminfo, but not in the per-node meminfo files, even though we track the information on a per-node basis. Printing it there can help track down dynamic pool bugs including the one in the follow-on patch.
