app/testpmd: fix tx vlan and qinq insert enable
Checks
Commit Message
Tx VLAN & QinQ insert enable need not depend on
Rx VLAN offload ETH_VLAN_EXTEND_OFFLOAD. Also enable
DEV_TX_OFFLOAD_VLAN_INSERT for tx_qinq_set() as it takes
both vlan id's.

Technically two different but related fix, should it be two separate patches,
what do you think?

Here I think intention is if QINQ is enabled 'tx_vlan_id' & 'tx_vlan_id_outer'
should be set by tx_qinq_set() not 'tx_vlan_set', and check is for that.
What do you think keeping same logic?
But of course check should be if 'ports[port_id].dev_conf.txmode.offloads' has
'DEV_TX_OFFLOAD_QINQ_INSERT' instead of above check.
