Subject: [PATCH 2/2] ipvs: fix crash in ip_vs_control_net_cleanup on unload

From: Julian Anastasov <ja@....bg>

	commit 14e405461e664b777e2a5636e10b2ebf36a686ec (2.6.39)
("Add __ip_vs_control_{init,cleanup}_sysctl()")
introduced regression due to wrong __net_init for
__ip_vs_control_cleanup_sysctl. This leads to crash when
the ip_vs module is unloaded.

	Fix it by changing __net_init to __net_exit for
the function that is already renamed to ip_vs_control_net_cleanup_sysctl.
