[PATCH v3 8/8] drm/drm-file: Show finer-grained BO sizes in drm_show_memory_stats

The current implementation will try to pick the highest available size
display unit as soon as the BO size exceeds that of the previous
multiplier.

By selecting a higher threshold, we could show more accurate size numbers.
