From: Huisong Li <lihuisong@huawei.com>
PF driver prints a warning on device that does not support auto-negotiation
when user does not configure "link_speeds" (default 0), which means
auto-negotiation. Currently, this warning information is printed in
dev_configure stage and a success is returned. Perhaps the user may call
dev_configure multiple times before dev_start for some reason or purpose.
In this case, this message may be printed multiple times. So this patch
moves it to dev_start stage.
Fixes: cfc9fe48c4d4 ("net/hns3: move link speeds check to configure")
