net: dsa: rtl8366: Fix up VLAN filtering
We get this regression when using RTL8366RB as part of a bridge
with OpenWrt:
WARNING: CPU: 0 PID: 1347 at net/switchdev/switchdev.c:291
switchdev_port_attr_set_now+0x80/0xa4
lan0: Commit of attribute (id=7) failed.
(...)
realtek-smi switch lan0: failed to initialize vlan filtering on this port
This is because it is trying to disable VLAN filtering
on VLAN0, as we have forgot to add 1 to the port number
to get the right VLAN in rtl8366_vlan_filtering(): when
we initialize the VLAN we associate VLAN1 with port 0,
VLAN2 with port 1 etc, so we need to add 1 to the port
offset.
