Although the meta-flow says it's 12 bit wide, in reality the VLANV_VID
field can hold a 13 bit value because bit 12 expresses the presense of
vlan header in certain OpenFlow versions (see
http://www.openvswitch.org/support/dist-docs/ovs-fields.7.txt)
Therefore, override the vlan_vid length so that the parser does not fail
when it encounters this 13bit wide vlan_vid fields
