### What this PR does / why we need it?
This PR fixes a `TypeError` in
`tests/e2e/nightly/single_node/ops/singlecard_ops/triton/test_penality.py`
that was causing nightly test failures. The `torch.rand()` function was
being called with the `device` string as a positional argument, which is
incorrect. This has been corrected to use the `device` keyword argument.
