mlx4_core: disable mlx4_QP_ATTACH calls from guests if master is doing flow steering.

Old upstream kernel guests do not detect if device-enabled flow
steering is activated by the master. If DMFS is activated,
the master should return error to guests which try to use
the B0-steering flow calls (mlx4_QP_ATTACH).
