net/fsl: xgmac_mdio: fix return value check in xgmac_mdio_probe()
In case of error, the function devm_ioremap() returns NULL pointer
not ERR_PTR(). The IS_ERR() test in the return value check should
be replaced with NULL test.
Fixes: 1d14eb15dc2c ("net/fsl: xgmac_mdio: Use managed device resources")
