Sergey Sharybin 8694274538 Fix #150049: Incorrect instance render using BVH2 spatial splits
BVHSpatialSplit::split_*_primitive() methods only access positions at
the time step 0 and do not consider motion blur positions. This leads
to situations when BVH bounding boxes are too small.

For now disable spatial splits for BLAS when object has motion blur.
This is simplest and safest solution for the upcoming release. It is
possible to tweak the code in the BVHSpatialSplit in the future.
