net/mlx5: Add HWS as secondary steering mode

Add HW Steering (HWS) as a secondary option for device steering mode. If
the device does not support SW Steering (SWS), HW Steering will be used
as the default, provided it is supported. FW Steering will now be
selected as the default only if both HWS and SWS are unavailable.
