From: Grzegorz Szczurek <grzegorzx.szczurek at intel.com>
If ADq is enabled for a VF, then actual number of queue pair
is a number of currently available traffic classes for this VF.
Without this change the configuration of the rx/tx queues
fails with error.
Fixes: d29e0d233e0d ("i40e: missing input validation on VF message handling by the PF")
