ipvs: fix info leak in getsockopt(IP_VS_SO_GET_TIMEOUT)
If at least one of CONFIG_IP_VS_PROTO_TCP or CONFIG_IP_VS_PROTO_UDP is not set, __ip_vs_get_timeouts() does not fully initialize the structure that gets copied to userland and that for leaks up to 12 bytes of kernel stack. Add an explicit memset(0) before passing the structure to __ip_vs_get_timeouts() to avoid the info leak.
