1.12: inference cache CI failure

[maleadt]

Seems to have regressed recently:

No Captured Logs for test item "PTX precompile" at test/ptx_tests.jl:354 on worker 2180
Error in testset "Inference caching" on worker 2180:
Test Failed at /home/runner/work/GPUCompiler.jl/GPUCompiler.jl/test/ptx_tests.jl:406
  Expression: check_presence(identity_mi, token)

1.12 is part of CI now, and doesn't fail.
