generic: rtl8366_smi: only assign pvid if no pvid was set yet
Only assign a pvid if the current pvid is 0. Fixes using mixed tagged and untagged traffic on a port and the untagged vlan isn't the last one of which the port is a member. Tested on RTL8366S and RTL8367R. Fixes #8501. Signed-off-by: Jonas Gorski <jogo@openwrt.org> SVN-Revision: 35227
