Zhengchao Shao 931f56d59c ipvs: fix WARNING in __ip_vs_cleanup_batch()
[ Upstream commit 3d00c6a0da ]

During the initialization of ip_vs_conn_net_init(), if file ip_vs_conn
or ip_vs_conn_sync fails to be created, the initialization is successful
by default. Therefore, the ip_vs_conn or ip_vs_conn_sync file doesn't
be found during the remove.

The following is the stack information:
name 'ip_vs_conn_sync'
