  Now in cmd_tx_vlan_set_parsed function, we check the vlan_offload
capability first, if it's a invalid port we'll get a prompt saying
"Error, as QinQ has been enabled.". So we should always make sure
that we get a valid port_id first before we check other information.
It's the same problem for cmd_tx_vlan_set_qinq_parsed.

Meanwhile, tx_vlan reset operation is simple enough to be put directly
into tx_vlan_set and tx_qinq_set function.
