[SYCL] Update bfloat16.cpp test to pass in no-assert mode

Test was modified at #6524

Change fixes post-commit issue in no-asserts mode

[pvchupin]

Actually that doesn't work. It looks like asserts are not supported in sycl. Need some other solution.

[aelovikov-intel]

Good enough to fix post-commit failures. I'd expect @rdeodhar to follow-up post-commit if anything could be improved.

HIP failure in max_local has been reported in #7604.

[pvchupin]

@steffenlarsen, do you have any idea why these appeared on HIP? I've seen it in a few other PRs as well but cannot easily connect to any recent change.

It looks like LIT is having trouble reading some exit code for one of the RUN lines. It is curious that it only happens for HIP, but the failure itself is not very informative.

Changes look good for now.
