net: dsa: rtl8366: Check VLAN ID and not ports
[ Upstream commit e8521e53cca584ddf8ec4584d3c550a6c65f88c4 ]
There has been some confusion between the port number and
the VLAN ID in this driver. What we need to check for
validity is the VLAN ID, nothing else.
The current confusion came from assigning a few default
VLANs for default routing and we need to rewrite that
properly.
Instead of checking if the port number is a valid VLAN
ID, check the actual VLAN IDs passed in to the callback
one by one as expected.
