[HOU-4655] VRay 7 Multi id material GPU bug

[chadstevens]

Hi Chaos. Thanks for Vray 7 for Houdini, it's really great to have.

I have noticed a bug in GPU mode when using multi id material node, it's not a problem in CPU, only GPU both (RTX and Cuda)
This worked fine in VRay 6.2

I'm running Houdini 19.5.805 and VRay 7.00.10

I've attached a few screenshots and a hip file for easy debugging
