[dpdk-dev] [PATCH v1] net/i40e: fix memory leak for dev reset

[Zhirun Yan]

Before this patch port reset will call i40evf_dev_uninit() and
i40evf_dev_init(), i40evf_dev_uninit() will call
i40e_dev_free_queues to free queues. If set
dev->data->nb_tx_queues = 0 in i40evf_dev_close, the next time
config queue will never free these queues.

Fixex: 6b4537128394 ("i40e: free queue memory when closing")
