  [OpenMP] Fix seg fault in libomptarget when using Info with multiple threads

Summary:
One option for the LIBOMPTARGET_INFO environment variable is to print the current status of the device's data mappings. These are a shared resource among threads so this needs to be protected when using multiple streams.
