net: dsa: qca8k: fix mdb add/del case with 0 VID
The qca8k switch doesn't support using 0 as VID and require a default
VID to be always set. MDB add/del function doesn't currently handle
this and are currently setting the default VID.
Fix this by correctly handling this corner case and internally use the
default VID for VID 0 case.
