Do not take cumulative network stats anymore ... Use two maps to record the details of network stats and swap and clean up after system server pulls the stats. The kernel program checks the bpf map currently enabled before updating the stats and updates on the corresponding map. Remove the TAG_STATS_MAP since we don't need to worry about uid stats overflow problem. All the stats can be stored in the same map until system server scrapes the stats and clean it up.
