Failing OpenMP target test

[rhornung67]

Describe the bug

An execution policy used in our GitLab CI for OpenMP target fails testing frequently: https://github.com/LLNL/RAJA/pull/1780/files#diff-a158c5ef165297aa9c906b40d94217695ef4151c7fbb5ee907e15ccf804926a2R83

To Reproduce

Compile the code on lassen with the compiler specified in our GitLab job file. Note that test fails similarly with other versions of the clang+cuda compiler.

Expected behavior

The test should pass and has passed in the past.

Compilers & Libraries (please complete the following information):

• Compiler & version: clang 16.0.6.cuda.11.8.0.gcc.11.2.1
• CUDA version (if applicable): 11.8.0
