rs_lock was used to protect rs_table (hash table) from updaters (under global mutex) and readers (packet handlers). We can remove rs_lock by using RCU lock for readers. Reclaiming dest only with kfree_rcu is enough because the readers access only fields from the ip_vs_dest structure. Use hlist for rs_table. As we are now using hlist_del_rcu, introduce in_rs_table flag as replacement for the list_empty checks which do not work with RCU. It is needed because only NAT dests are in the rs_table.
