child_device_type argument is responsible for selection.

Usage examples:

DirectX 11
-init_hw_device qsv:hw,child_device_type=d3d11va

DirectX 9
-init_hw_device qsv:hw,child_device_type=dxva2

This change seems...odd? It certainly doesn't do anymore what the
commit title indicates what it might do.
