[PATCH net-next 11/12] net: hns3: add initialization for nic state

[Huazhong Tan]

From: Jian Shen <shenjia...@huawei.com>

This patch adds initialization for nic state, sets flag
HNS3_NIC_STATE_DOWN when initialize, clears it before
vectors and napi being enabled in the hns3_nic_net_up(),
and sets it back in the error handler.
