These functions are wrappers to some testpmd functions, and those
functions already have invalid port check, like 'tx_vlan_set()'
Agree that check should be in these functions, but to prevent the
duplicated checks, what do you think to remove checks from internal
functions? ('tx_vlan_set', 'tx_qinq_set' & 'tx_vlan_reset').
