Subject: [PATCH] netfilter: ipvs: ip_vs_sync: Remove unused variable

From: Fabio Estevam <fabio.estevam@...escale.com>

Variable 'ret' is not used anywhere and it causes the following build warning: 

net/netfilter/ipvs/ip_vs_sync.c: In function 'sync_thread_master':
net/netfilter/ipvs/ip_vs_sync.c:1640:8: warning: unused variable 'ret' [-Wunused-variable]
