In revision 0x20, we use vlan id != 0 to check whether a vlan tag
has been offloaded, so vlan id 0 is not supported.
In revision 0x21, rx buffer descriptor adds two bits to indicate
whether one or more vlan tags have been offloaded, so vlan id 0
is valid now.
This patch seperates the handle for vlan id 0, add vlan id 0 support
for revision 0x21.
