Return proper type when sp_get_port_transport() fails
The above function must always return an 'enum sp_transport'. So, return NATIVE if no port is present because its effective meaning within the API is "you shouldn't call any transport-specific functions for this port handle". Fixes bug #1531. Signed-off-by: Wolfram Sang <wsa@kernel.org>
