From: Chengchang Tang <tangchengchang at huawei.com>

According to the programming guide, the rte_eal_init should be used pairs
with rte_eal_cleanup.

This patch add rte_eal_cleanup to this example to encourage new users of
DPDK to use it.

Fixes: aec9c13c5257 ("eal: add function to release internal resources")
