[spp] [PATCH 2/4] spp_nfv: fix incorrect deleting for ring port

[x-fn-spp@sl.ntt-tx.co.jp]

From: Hideyuki Yamashita <yamashita.hideyuki@po.ntt-tx.co.jp>

Spp_nfv uses `rte_eal_hotplug_remove()` in `dev_detach_by_port_id()` to
delete a ring. However, it is wrong because it causes an error when
adding the same ring again. This update is to use `rte_eth_dev_stop()`
and `rte_eth_dev_close()` as correct manner.
