net/iavf: fix memory leak in large VF

[ upstream commit 20aa3a8 ]

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: 9cf9c02 ("net/iavf: add enable/disable queues for large VF")
