[PATCH] net/nfp: fix coredump problem when testpmd exit

[PATCH] net/nfp: fix coredump problem when testpmd exit

[Chaoyong He]

The ".dev_close" should not call rte_eth_dev_release_port() API
directly, the rte_eth_dev_close() API will do it.

Fixes: 831c44ab7869 ("net/nfp: add flower PF related routines")
