net: hns3: fix for getting autoneg in hns3_get_link_ksettings 

This patch fixes a bug for ethtool's get_link_ksettings().
When phy exists, we should get autoneg from phy rather than from mac.
Because the value of mac.autoneg is invalid when phy exists.

Fixes: 496d03e (net: hns3: Add Ethtool support to HNS3 driver)
