net/mlx5e: TC, Reject forwarding from internal port to internal port

net/mlx5e: TC, Reject forwarding from internal port to internal port

Reject TC rules that forward from internal port to internal port
as it is not supported.

This include rules that are explicitly have internal port as
the filter device as well as rules that apply on tunnel interfaces
as the route device for the tunnel interface can be an internal
port.

Fixes: 27484f7170ed ("net/mlx5e: Offload tc rules that redirect to ovs internal port")
