vkd3d-shader: Remove the workaround for sample_c.

Browse Source 
The current workaround is broken for texture cube arrays, which already have 4
components.

Sampling with the components not packed together apparently succeeds with newer
NVidia drivers, so just remove the workaround. Tested with 470.103.01 on a GTX
1060.
