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.
