net: dsa: lantiq_gswip: Minor code style improvements
Use one code block when returning because the interface type is unsupported and also check if some unsupported port gets configured. In addition fix a double the and use dsa_is_cpu_port() instated of manually getting the CPU port. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: David S. Miller <davem@davemloft.net>
