Material Function with Texture Size Texture Property will cause a Crash

By accessing the texture property for texture size will cause a crash.

Attached image for material graph.

Tested in:
4.10.4 Texture Size Texture Property did not exist
4.11.- CL-2927265
4.12 Dev-Platform - CL-2931152

1. Open UE4
2. Create a Material Function
3. Recreate the Material Graph in the attached image

Results: The editor will crash

Expected: The editor will not crash
