Subject: net: hns3: Fixes the wrong IS_ERR check on the returned phydev value
Patch-mainline: v4.14-rc1
Git-commit: 752b06946cc99534a7a4a11b7196e9a1e3d7e098
References: bsc#1104353 FATE#326415

This patch removes the wrong check being done for the phy device being
returned by the mdiobus_get_phy() function. This function never returns
the error pointers.

Fixes: 256727da7395 ("net: hns3: Add MDIO support to HNS3 Ethernet
Driver for hip08 SoC")
