dpdk: fix rte mempool for rx_queues
Change dpdk_ops_vpp_get_count() return value from 0
to actual available pool size;
For some drivers/envs(azure,vmbus) rx_queue size
will be zero and the only 1 element will be created
(0 + 1)
When more than one packet will arrive, it will cause
SEGFAULT
Type: fix
