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.
