When an application invokes rte_eth_dev_configure consecutively without
setting up Rx/Tx queues, it will incorrectly return error while trying
to restore Rx/Tx queue configuration.
Fix configuration sequence by checking if any Rx/Tx queues are
previously configured before trying to restore them.
Fixes: 548b5839a32b ("net/octeontx2: add device configure operation")
