[ Upstream commit 9802d21e7a0b0d2167ef745edc1f4ea7a0fc6ea3 ]
The tot_stats estimator is started only when CONFIG_SYSCTL is defined. But it is stopped without checking CONFIG_SYSCTL. Fix the crash by moving ip_vs_stop_estimator into ip_vs_control_net_cleanup_sysctl.
The change is needed after commit 14e405461e664b ("IPVS: Add __ip_vs_control_{init,cleanup}_sysctl()") from 2.6.39.
