net: stmmac: failure to probe without MAC interface specified

Browse source

Alexander Stein reports that commit a014c35556 ("net: stmmac: clarify
difference between "interface" and "phy_interface"") caused breakage,
because plat->mac_interface will never be negative. Fix this by using
the "rc" temporary variable in stmmac_probe_config_dt().
