[dpdk-dev] [PATCH v4 4/5] net/tap: fix close a valid fd

[wangyunjian]

From: Yunjian Wang <wangyunj...@huawei.com>

The internal structure is freed and set to NULL in the
rte_eth_dev_release_port() and zero is a valid fd. Ultimately
leads to a valid fd was closed by mistake.

Fixes: 3101191c63ab ("net/tap: fix device removal when no queue exist")
