Subject: [PATCH net-next 09/12] net: hns3: fix pause configure fail problem

When configure pause, current implementation returns directly
after setup PFC without setup BP, which is not sufficient.

So this patch fixes it, only return while setting PFC failed.

Fixes: 44e59e375bf7 ("net: hns3: do not return GE PFC setting err when initializing")
