Ater the conversion of dwmac-sunxi into a standalone platform driver, the .init function is called before calling into the stmmac driver core, but .exit is not called to clean up if stmmac returns an error. This patch fixes the probe error path. This properly cleans up and releases resources when the driver core fails to probe.
