[PATCH net] net: stmmac: dwmac-intel-plat: fix error return code in intel_eth_plat_probe()

[Zhang Changzhong]

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.

Fixes: 9efc9b2b04c7 ("net: stmmac: Add dwmac-intel-plat for GBE driver")
