SYCL :: OneapiDeviceSelector/sub-devices.cpp reached timeout on an unrelated change

[AlexeySachkov]

Describe the bug

Discovered in #14624. The patch should effectively be a non-functional change, but by some reason the test still failed.

To reproduce

Launching the test should be trivial, but it is likely that environment is involved here, so not sure how easy it will be to reproduce.

Environment

• OS: Linux
• Target device and vendor: NVIDIA GPU
• DPC++ version: most recent intel/llvm
• Dependencies version:

Platform [#1]:
    Version  : CUDA 12.1
    Name     : NVIDIA CUDA BACKEND
    Vendor   : NVIDIA Corporation
    Devices  : 1
        Device [#0]:
        Type              : gpu
        Version           : 8.6
        Name              : NVIDIA A10G
        Vendor            : NVIDIA Corporation
        Driver            : CUDA 12.1
Images are not fully supported by the CUDA BE, their support is disabled by default. Their partial support can be activated by setting SYCL_PI_CUDA_ENABLE_IMAGE_SUPPORT environment variable at runtime.

Note that the test didn't find any devices at all, which is weird
