cxl: Move QoS class to be calculated from the nearest CPU

Browse source

Retrieve the qos_class (QTG ID) using the access coordinates from the
nearest CPU rather than the nearst initiator that may not be a CPU.
This may be the more appropriate number that applications care about.

For most cases, access0 and access1 have the same values.
