i40e: Fix calculating the number of queue pairs
[ Upstream commit 0bb050670ac90a167ecfa3f9590f92966c9a3677 ]
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")
