Subject: net: hns3: use the correct interface to stop|open port
Patch-mainline: v5.1-rc1
Git-commit: fc0c174f4223b7340999e1b3004dbc3b3b9b06de
References: bsc#1126390

dev_close() stop the netdev and the service base on the netdev
will stop. But ndev->netdev_ops->ndo_stop() may only stop HW
and stack queue, the service base on the netdev can still work.
