At queue configure stage always allocate space for maximum possible number (RTE_MAX_QUEUES_PER_PORT) of queue pointers. That will allow 'fast' inline functions (eth_rx_burst, etc.) to refer pointer to internal queue data without extra checking of current number of configured queues. That would help in future to hide rte_eth_dev and related structures. It means that from now on, each ethdev port will always consume: ((2*sizeof(uintptr_t))* RTE_MAX_QUEUES_PER_PORT) bytes of memory for its queue pointers. With RTE_MAX_QUEUES_PER_PORT==1024 (default value) it is 16KB per port.
