[dpdk-dev] [RFC V2 2/2] app/testpmd: fix starting failed with queue-stats-mapping

["Min Hu (Connor)" <humin29@huawei.com>]

From: Huisong Li <lihuisong@huawei.com>

testpmd fails to start with "--rx-queue-stats-mapping" and
"--tx-queue-stats-mapping", which is caused by the failure and exit of
'map_port_queue_stats_mapping_registers' function. By default,
the configuration of queue statistics mapping in the initialization
process is implemented in the 'init_port_config' function. However,
the dev_configure interface is not called to configure the NIC
and dev->data-nb_rx/tx_queues is zero. As a result,
'rte_eth_dev_set_tx/rx_queue_stats_mapping' function fails to verify
the queue_id. Therefore, it is necessary to move
'map_port_queue_stats_mapping_registers' from 'init_port_config'
to 'start_port' function.

Fixes: 013af9b6b64f6e7 ("app/testpmd: various updates")
