From: Huazhong Tan <tanhuazh...@huawei.com>
While doing DOWN, the calling of napi_disable() may not return, since the
napi_complete() in the hns3_nic_common_poll() will never be called when
HNS3_NIC_STATE_DOWN is set. So we need to call napi_complete() before
checking HNS3_NIC_STETE_DOWN.
Fixes: ff0699e04b97 ("net: hns3: stop napi polling when HNS3_NIC_STATE_DOWN is
set")
