[dpdk-dev] [PATCH v3 4/5] net/tap: fix close a valid fd

[wangyunjian]

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

The internals is freed and setted NULL in the rte_eth_dev_release_port()
and zero is a valid fd. As a result, a valid fd is incorrectly closed.

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