IB/mlx5: Add port_xmit_wait to counter registers read
Add port_xmit_wait to the error counters read by mlx5_ib_process_mad to ensure sysfs port counter provides correct value for PortXmitWait. Otherwise the sysfs port_xmit_wait file always contains zero. The previous MAD_IFC implementation populated this counter, but it was removed during the migration to PPCNT for error counters (32-bit only).
