[ Upstream commit 27b5bf49f0924fd62d2b1ef8467b40773973da34 ]
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().
