dptx: Improved sink reordering.

Browse source 
The sink reordering would fail on retrieval of tiling information from a sink
that does not have a Tiled Display Topology (TDT) data block. This behavior is
incorrect since subsequent sinks may be a part of a tiled display.
Modified the function to be void.
