net: hns3: fix for getting auto-negotiation state in hclge_get_autoneg

When phy exists, we use the value of phydev.autoneg to represent the
auto-negotiation state of hardware. Otherwise, we use the value of
mac.autoneg to represent it.

This patch fixes for getting a error value of auto-negotiation state in
hclge_get_autoneg().
