vdpa/mlx5: Update Control VQ callback information

elic307i · mstsirkin · commit 40f2f3e94178 · 2022-06-24T02:49:47.000-04:00
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.
