Rename "ring_mirror_list" to "pending_list", to describe what something is, not what it does, how it's used, or how the hardware implements it.
This also abstracts the actual hardware implementation, i.e. how the low-level driver communicates with the device it drives, ring, CAM, etc., shouldn't be exposed to DRM.
The pending_list keeps jobs submitted, which are out of our control. Usually this means they are pending execution status in hardware, but the latter definition is a more general (inclusive) definition.
