[PATCH] hwmon: (w83627ehf) Fix a resource leak in probe

[Dan Carpenter <dan.carpenter@xxxxxxxxxx>]

Smatch has a new check for resource leaks which found a bug in probe:

    drivers/hwmon/w83627ehf.c:2417 w83627ehf_probe()
    warn: 'res->start' not released on lines: 2412.

We need to clean up if devm_hwmon_device_register_with_info() fails.

Fixes: 266cd5835947 ("hwmon: (w83627ehf) convert to with_info interface")
