Revert "net: hns3: fix pause config problem after autoneg disabled"
This reverts commit 3bda2e5df476417b6d08967e2d84234a59d57b1c.
According to discussion with Andrew as follow:
https://lore.kernel.org/netdev/09eda9fe-196b-006b-6f01-f54e75715961@huawei.com/
HNS3 driver needs to separate pause autoneg from general autoneg, so revert
this incorrect patch.
