ACPI: Use the return result of ACPI lid notifier chain correctly
On some laptops it will return NOTIFY_OK(non-zero) when calling the ACPI LID
notifier. Then it is used as the result of ACPI LID resume function, which
will complain the following warning message in course of suspend/resume:
>PM: Device PNP0C0D:00 failed to resume: error 1
This patch is to eliminate the above warning message.
