When using testpmd, sometimes we forget the right order of port_id and
vid in "tx_vlan set (port_id) vlan_id[, vlan_id_outer]\n" command, and
input "tx_vlan set 51 0", we'll get a strange prompt saying "Error, as
QinQ has been enabled.".

In cmd_tx_vlan_set_parsed function, the first thing we do is checking
the port's vlan_offload capability, rather than checking validity of the
port_id, therefore if it's an invalid port_id we'll get the above wrong
message. We should always make sure that we get a valid port_id before
we do other things.

It's the similar issue for cmd_tx_vlan_set_qinq_parsed function.

Fixes: 92ebda07ee58 ("app/testpmd: add qinq stripping and insertion")

v4:
* Added fixes line.

v3:
* Reworded the patch subject and commit message, added detail for reproducing
  the bug.

* Reordered the definitions of cmd_tx_vlan_set_portid and cmd_tx_vlan_set_vlanid
  to keep in consistency with cmd_tx_vlan_set.tokens.

v2:
* Removed the bug fix unrelated code change to make this patch a pure bug fix
  patch.

* Fixed the "PATCH 1/2" mistake in the patch title, rewrote the subject.
