Fix #127240: Deforming motion blurred point clouds do not render under certain conditions

Browse Source 
Deforming motion blurred point clouds do not render in Cycles
HIP-RT when BVH timesteps != 0 if Blender is launched with
debug memory.

The root cause is that the size of allocated memory for the
bounding boxes is reported to HIP-RT not the number of valid
bounding boxes.
