Correct free/used typo in Prometheus 'connection_pool' gauge cleanup #4470

In MySQL_HostGroups_Manager::p_update_connection_pool(), in the section that cleans up connection pool gauge metrics associated with missing servers, this is correcting a typo switching "free" and "used" such that the "Remove" method is being called on the wrong gauge.
