app/testpmd: fix log of start command

Application can provide 0 for ring size to use default values. To not
log zero for that case get configured ring size from device.

Call the rte_eth_rxq_info_get() and rte_eth_txq_info_get() functions
to update the number of rx and tx descriptors.

Fixes: d44f8a485f5d ("app/testpmd: enable per queue configure")
