net/ixgbe: fix the failure of number of Tx queue check

Browse Source 
Tx_q check fails when the SRIOV is active and tx_q > rx_q. It has
to use the maximum HW queue number for calculation, to get the
right number of queue can be used.

Fixes: 27b609cbd1c6 ("ethdev: move the multi-queue mode check to specific drivers")
