hwmon: (gpio-fan) Fix fan_ctrl_init error path
In current implementation, the sysfs entries is not removed before return -ENODEV.
Creating the sysfs attribute should be the last thing done by the function,
after all the rest has been successful.
Otherwise there is a small window during which user-space can access the attribute
but the driver isn't ready to deal with the requests.
Fix it by moving sysfs_create_group to be the last thing done by the function.
