(Shared) memory overfill causing device hang

[milank94]

Describe the bug
Running benchmark with high loop_counts will cause the (shared) memory to fill up with, leading to a device hang.

Need to adjust the benchmark.py script to only store the input labels and ouputs for the first loop iteration into Python list objects.

To Reproduce
Steps to reproduce the behavior:
python benchmark.py -d tt -m yolo_v5 -c s --task object_detection -mb 128 --loop_count 32 -opt 4 --save_output
