[ Upstream commit 269f9883fe254d109afdfc657875c456d6fabb08 ]
The Granular QoS per VF feature must be enabled in FW before it can be
used.
Thus, the driver cannot modify a QP's qos_vport value (via the UPDATE_QP FW
command) if the feature has not been enabled -- the FW returns an error if
this is attempted.
Fixes: 08068cd568 ("net/mlx4: Added qos_vport QP configuration in VST mode")
