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

### 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
