[OpenMP][libomptarget] Fix run region async condition

[kevinsala]

Summary

This patch fixes a condition in the openmp/libomptarget/src/device.cpp file. The code was checking if the run_region plugin API function was implemented, but it should actually check the run_region_async function instead.

Hi Shilei Tian,
I don't have access to push commits to the LLVM repository. Would you mind pushing this fix commit for me?
Thank you in advance
