Subject: net: hns3: cleanup mac auto-negotiation state query
Patch-mainline: v4.16-rc1
Git-commit: 492cd1db582d9e91c6db23a054bf63365ac84dc7
References: bsc#1104353 FATE#326415

When checking whether auto-negotiation is on, driver only needs to
check the value of mac.autoneg(SW) directly, and does not need to
query it from hardware. Because this value is always synchronized
with the auto-negotiation state of hardware.

This patch removes the mac auto-negotiation state query.
