mlx5: DR, Enable SW Steering RX/TX domains

Till the use of force-loopback QP we didn't support RX/TX DR-steering
due to a missing recovery mechanism in case the GID was changed by the
user.
Now when using loopback QP there is no need to worry about gid staff and
we able to support RX/TX steering like it's done with FDB steering.
