[Bug][Hexagon] Relax Hexagon integration tests pass in simulator but fail on device

[psrivas2]

Relax Hexagon integration tests are failing on Hexagon device but passing in simulator.

Repro To repro you will need to have access to hexagon device.

Follow the instructions to compile TVM and setup to run hexagon tests.

./tests/scripts/task_python_hexagon.sh

Right now it gets stuck at

Thanks for updating the bug @yongwww.

However, we have to keep this open because the #238 partially fixes the issue. Tests when run individually pass but fail when all of them run together using the command: pytest tests/python/contrib/test_hexagon/test_relax_integration.py. So further investigation is needed.
