[dpdk-dev] [PATCH v1] net/iavf: fix not release memory issue in large VF

[Ting Xu <ting.xu@intel.com>]

This patch fixed the issue that the memory allocated for structure
virtchnl_del_ena_dis_queues is not released at the end of the functions
iavf_enable_queues_lv, iavf_disable_queues_lv and iavf_switch_queue_lv.

Fixes: 9cf9c02bf6ee ("net/iavf: add enable/disable queues for large VF")
Cc: stable@dpdk.org
