ACPI: asus_acpi: Do not load if no device has been found
asus_acpi_init() has a hack to prevent the driver from loading
when asus_hotk_add() fails. However, it was returning the successful
return value of acpi_bug_registger_driver() on failure. This caused
an oops on unload. Instead it should return -ENODEV.
