Cycles: Fix infinite update when using duplis
The issue was caused by usage of address of dupli-object (which will vary
from iteration process to iteration process) as something denoting whether
we've got the data synchronized to Cycles or not.
For now solved by using address of original object (the one DupliObject
points to) as a pointer for the map.
Need to do more thoughts about this.
