mdio_bus: Fix PTR_ERR applied after initialization to constant

Browse Source 
Fix coccinelle warning:

./drivers/net/phy/mdio_bus.c:67:5-12: ERROR: PTR_ERR applied after initialization to constant on line 62
./drivers/net/phy/mdio_bus.c:68:5-12: ERROR: PTR_ERR applied after initialization to constant on line 62

Fix this by using IS_ERR before PTR_ERR
