rGf6c2984a090e: [OpenMP][NVPTX] Fixed a compilation error in deviceRTLs caused by unsupported…
Summary

ptx71 is not supported in release version of LLVM yet. As a result,
the support of CUDA 11.2 and CUDA 11.1 caused a compilation error as mentioned
in D97004. Since the support in D97004 is just a WA for releease, and we'll not
use it in the near future, using ptx70 for CUDA 11 is feasible.
