net: enetc: Fix use after free issue in fsl_enetc.c

If ethernet connected to SFP, like this:

&enetc_port0 {
            phy-connection-type = "sgmii";
            sfp = <&sfp0>;
            managed = "in-band-status";
            status = "okay";
};

Then enetc_config_phy returns -ENODEV and the memory containing the mdio interface is freed.
It's better to unregister and free mdio resources.
