IB/mlx5: Set flow steering capability bit
Flow steering is supported by mlx5 device when the following features are supported by firmware: 1. NIC RX flow table. 2. Device has enough flow steering levels. 3. Atomic modification of flow table entry. 4. Flow tables chaining. To check if flow steering is supported it's enough to check if the driver opened the mlx5 bypass namespace.
