platform/x86: int3472: Avoid crash in unregistering regulator gpio
When int3472 is loaded before GPIO driver, acpi_get_and_request_gpiod()
failed but the returned gpio descriptor is not NULL, it will cause panic
in later gpiod_put(), so set the gpio_desc to NULL in register error
handling to avoid such crash.
