For tcp_crr server, a new flow is created for each short-lived
connection. If we collect stats, flow's neper_stat will be added
to worker thread's neper_stats, and won't be freed until the worker
thread ends. It will use a lot of memory (~1GB/sec) and cause test
failures.
For other four workloads including tcp_crr client, the number of
flows is specified by command line flag, so the memory useage is
stable.
