Subject: [PATCH net-next v4 3/3] ipvs: log additional sync daemon parameters

Add new multicast parameters to log messages when sync daemons start.

Commit e4ff67513096 ("ipvs: add sync_maxlen parameter for the sync
daemon") and commit d33288172e72 ("ipvs: add more mcast parameters for
the sync daemon") added additional multicast parameters, but didn't add
them to the log messages when the sync daemons started.
