Cycles: Fix crash changing image after recent OpenCL changes

Steps to reproduce:
- Create shader Image texture -> Diffuse BSDF -> Output. Do NOT select image yet!
- Start viewport render.
- Select image from the ID browser of Image Texture node.

Thing is: with the memory manager we always need to inform device that memory
was freed.
