ipvs: optimize rates reading
Move the estimator reading from estimation_timer to user context. ip_vs_read_estimator() will be used to decode the rate values. As the decoded rates are not set by estimation timer there is no need to reset them in ip_vs_zero_stats. There is no need ip_vs_new_estimator() to encode stats to rates, if the destination is in trash both the stats and the rates are inactive.
