net/ixgbe: fix memzone leak on queue re-configure

Normally when closing the device the queue memzone should be
freed. But the memzone will be not freed, when device setup
ops like:

rte_eth_bond_slave_remove
-->__eth_bond_slave_remove_lock_free
---->slave_remove
------>rte_eth_dev_internal_reset
-------->rte_eth_dev_rx_queue_config
---------->eth_dev_rx_queue_config
------------>ixgbe_dev_rx_queue_release
rte_eth_dev_close
-->ixgbe_dev_close
---->ixgbe_dev_free_queues
------>ixgbe_dev_rx_queue_release
      (not been called due to nb_rx_queues and nb_tx_queues are 0)

And when queue number is changed to small size, the BIG memzone
queue index will be lost. This will lead to a memory leak. So we
should release the memzone when releasing queues.
