ethdev: add queue state in queried queue information

Browse Source 
Currently, upper-layer application could get queue state only
through pointers such as dev->data->tx_queue_state[queue_id],
this is not the recommended way to access it. So this patch
add get queue state when call rte_eth_rx_queue_info_get and
rte_eth_tx_queue_info_get API.

Note: After add queue_state field, the 'struct rte_eth_rxq_info' size
remains 128B, and the 'struct rte_eth_txq_info' size remains 64B, so
it could be ABI compatible.
