net: hns3: return error code when function fails

Browse source

[ Upstream commit 03ca7c8c42 ]

Currently, in hclge_mii_ioctl(), the operation to
read the PHY register (SIOCGMIIREG) always returns 0.

This patch changes the return type of hclge_read_phy_reg(),
returning an error code when the function fails.
