4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Yunsheng Lin <linyunsheng@huawei.com>

[ Upstream commit 3f8601f0f5716c4e63a9f215bbc581df42859d61 ]

When ping is runnig and user executes the loopback selftest, the
ping cmd will stop and exit.

This patch fixes it by using the hns3_nic_net_open/stop to offline
the netdev when doing loopback selftest.

Fixes: c39c4d98dc65 ("net: hns3: Add mac loopback selftest support in hns3 driver")
