Crash on vk::DescriptorSetUpdater::Update when a shader variant is compiled with DOTS_INSTANCING_ON with material that doesn't use DOTS-backed data

Steps to reproduce:
1. Open the attached project “IN-141039”
2. In the Project window, open “Assets” → “MinimalMaterials”
3. Make sure “Crash Type” is set to “Crash”
4. In the Project window, open “Assets” → “Scenes” → “SampleScene”
5. Build and run
6. Open the Player on your mobile phone

Actual result: When loading “Subscene” and a sphere with custom-made material the Player crashes
Expected result: When loading “Subscene” player doesn't crash
