Currently majority of fast-path ethdev ops take pointers to internal queue data structures as an input parameter. While eth_rx_queue_count() takes a pointer to rte_eth_dev and queue index. For future work to hide rte_eth_devices[] and friends it would be plausible to unify parameters list of all fast-path ethdev ops. This patch changes eth_rx_queue_count() to accept pointer to internal queue data as input parameter. While this change is transparent to user, it still counts as an ABI change, as eth_rx_queue_count_t is used by ethdev public inline function rte_eth_rx_queue_count().
