net/mlx5e: Add a check for the return value from mlx5_port_set_eth_ptys
Since the documentation for mlx5_toggle_port_link states that it should only be used after setting the port register, we add a check for the return value from mlx5_port_set_eth_ptys to ensure the register was successfully set before calling it.
