platform/x86: wmi: Always evaluate _WED when receiving an event
The ACPI WMI specification states: "The _WED control method is evaluated by the mapper in response to receiving a notification from a control method." This means that _WED should be evaluated unconditionally even if no WMI event consumers are present. Some firmware implementations actually depend on this behavior by storing the event data inside a queue which will fill up if the WMI core stops retrieving event data items due to no consumers being present Fix this by always evaluating _WED even if no WMI event consumers are present.
