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
------------>em_rx_queue_release
rte_eth_dev_close
-->eth_em_close
---->em_dev_free_queues
------>em_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.
