Cycles: Free hires smoke data from blender side after scene was fully synchronized
This happens if all object's smokes are backed to files and rendering is either
happening from command line of with locked interface.
The idea behind this change is to make as much memory available for path tracing
as possible, so after heavy swapping during synchronization period there's loads
of free memory to put important data back to RAM.
