Subject: [PATCH v2 5/5] mm: Rename zone_statistics() to numa_statistics()

Since the functionality of zone_statistics() updates numa counters, but
numa statistics has been separated from zone statistics framework. Thus,
the function name makes people confused. So, change the name to
numa_statistics() as well as its call sites accordingly.
