[dpdk-dev] [PATCH] net/iavf: fix mbuf leak

[Qiming Chen]

In the iavf_dev_rx_queue_start function, if the iavf_switch_queue
or iavf_switch_queue_lv function fails, the previously applied mbuf
is not released, resulting in leakage. The patch fixes the problem.
Fixes: 9cf9c02bf6ee ("net/iavf: add enable/disable queues for large VF")
