[PATCH v4] net/ixgbe: fix l3fwd start failed on PF

[Yanglong Wu <yanglong.wu@intel.com>]

L3fwd start failed on PF, for tx_q check failed.
That occurred when the SRIOV is active and tx_q > rx_q.
The tx_q is equal to nb_q_per_pool. The number of nb_q_per_pool
should equeal to max number of queues supported by HW not nb_rx_q.

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