Yaxun (Sam) Liu 800f26386c [CUDA][HIP] Fix delete operator for -fopenmp
When new operator is called in OpenMP parallel region,
delete operator is resolved and checked. Due to similar
issue fixed by https://reviews.llvm.org/D121765,
when resolving delete operator, the caller was not
determined correctly, which results in error as
shown in https://godbolt.org/z/jKhd8qKos.

This patch fixes the issue in a similar way as
https://reviews.llvm.org/D121765
