net: hns3: fix port setting handle for fibre port
For hardware doesn't support use specified speed and duplex
to negotiate, it's unnecessary to check and modify the port
speed and duplex for fibre port when autoneg is on.
Fixes: 22f48e24a23d ("net: hns3: add autoneg and change speed support for fibre port")
