Subject: [PATCH] net/i40e: ensure vector mode is not used with QinQ

[ upstream commit b6e2e78f5dbece33b64e742331ae949b7ead5373 ]

In rx vector mode, QinQ is not supported.
When hw_vlan_extend is set for QinQ ensure that
rx vector mode is not selected.

Fixes: 8e109464c022 ("i40e: allow vector Rx and Tx usage")
