Subject: [PATCH net-next] net: hns3: Fixes the wrong IS_ERR check on the returned phydev value

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")
