While a representor device in switchdev mode should use the mlx5_ib_query_q_counters_vport() function and query only the Q_Counters without the PPCNT counters and congestion control counters, since they aren't relevant for a representor device. Currently a non-representor switchdev device skips querying the PPCNT counters and congestion control counters, leaving them unupdated. Fix that by properly querying those counters for non-representor devices.
