module_api_global relies on a HCC only feature which allows host code to write to device variables. This feature does not exist in CUDA or hip-clang, which causes the sample not working in CUDA or hip-clang. This patch fixes the sample by using standard features of CUDA and hip-clang. The fixed sample works in HCC, CUDA and hip-clang.
