net: hns3: add error handling in hclge_ieee_setets
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")
