ixgbe: cleanup maximum number of tx queues
In the last patch I missed an unecessary min_t comparison.
This patch removes it, the path allocates at most
72 tx queues for 82599 and 24 for 82598 there is no need
for this check.
Additionally this sets MAX_[TX|RX]_QUEUES to 72. Which is
used as the size for the tx/rx_ring arrays. There is no
reason to have more tx_rings/rx_rings then num_tx_queues.
