SWDEV-445096 - Fix -O0 crash in OpenCL tests

- With https://gerrit-git.amd.com/c/lightning/ec/llvm-project/+/1002628 applied, at -O0 Kernel::dynamicParallelism() returns true but virtual queue isn't created
- This causes segfault inside VirtualGPU::submitKernelInternal() when getVQVirtualAddress() is called
