[dpdk-dev] [PATCH] ethdev: check if queues are allocated before getting info

[Ferruh Yigit]

A crash is detected when '--txpkts=#' parameter provided to the testpmd,
this is because queue information is requested before queues have been
allocated.

Adding check to queue info APIs
('rte_eth_rx_queue_info_get()' & 'rte_eth_tx_queue_info_get')
to protect against similar cases.

Fixes: ba2fb4f022fc ("ethdev: check if queue setup when getting queue info")
