[dpdk-dev] [PATCH] net/i40e: fix mbuf resource leakage problem

[chenqiming_huawei at 163.com]

From: Qiming Chen <chenqiming_huawei at 163.com>

In the i40evf_dev_rx_queue_start function, when the function
i40evf_switch_queue returns failed, the previously requested mbuf resource
is not released.

Fixes: 74b7496b0cb3 ("net/i40e: remove redundant queue id checks")
