net/mlx4_core: Fix return codes of unsupported operations

Browse Source 
Functions __set_port_type and mlx4_check_port_params returned
-EINVAL while the proper return code is -EOPNOTSUPP as a
result of an unsupported operation. All drivers should generate
this and all users should check for it when detecting an
unsupported functionality.
