[PATCH net-next 03/12] net: hns3: add error handling in hclge_ieee_setets

[Huazhong Tan]

From: Yunsheng Lin <linyunsh...@huawei.com>

Currently hclge_ieee_setets returns error directly when there is
error, which may cause netdev not up problem.

This patch adds some error handling when setting ETS configuration
fails.

Fixes: cacde272dd00 ("net: hns3: Add hclge_dcb module for the support of DCB 
feature")
