From: Eli Cohen <elic@xxxxxxxxxx>
commit 40f2f3e94178d45e4ee6078effba2dfc76f6f5ba upstream.
The control VQ specific information is stored in the dedicated struct
mlx5_control_vq. When the callback is updated through
mlx5_vdpa_set_vq_cb(), make sure to update the control VQ struct.
Fixes: 5262912ef3cf ("vdpa/mlx5: Add support for control VQ and MAC setting")
