[clang] [CUDA] Correctly set CUDA default architecture (PR #84017)

[Joseph Huber via cfe-commits]

https://github.com/jhuber6 created https://github.com/llvm/llvm-project/pull/84017

Summary:
We already had a special CUDA default that better tracked the state as
of modern CUDA installations. Recently this was bumped up to `sm_52`,
but there was a location that wasn't respecting this. Fix that.
