Subject: [PATCH net-next 2/3] i40e: remove unnecessary qv_info ptr NULL checks

From: Alexey Kodanev <aleksei.kodanev@...l-sw.com>

The "qv_info" ptr cannot be NULL when it gets the address of
an element of the flexible array "qvlist_info->qv_info".

Detected using the static analysis tool - Svace.
