[ Upstream commit e98365afc1e94ea1609268866a44112b3572c58b ]
If failed to register netdev, it needs to clear INITED state and stop
client in case of cause problem when concurrency with uninitialized
process of driver.
Fixes: a289a7e5c1d4 ("net: hns3: put off calling register_netdev() until client initialize complete")
