Fix T43311: using displacement shader crashes blender

Issue was caused by wrong order of scene device update, which could
lead to missing object flags in shader kernel.

This patch solves a bit more than that making sure objects flags are
always properly updated, so adding/removing volume BSDF will properly
reflect on viewport where camera might become being in volume and so.
