[PUSHED] OpenMP: Add omp_get_device_distances routine: Initialize NUMA node for NVIDIA GPUs [PR125877]

[Thomas Schwinge]

Fix-up for commit 8af1592882509fbead16e30fd2d056330a9609e4
"OpenMP: Add omp_get_device_distances routine [PR125877]".  Without this,
'libgomp/plugin/plugin-nvptx.c:GOMP_OFFLOAD_get_numa_node' returns random junk:

    /* Initialized to 0; to distinguish, save with offset.  */
    if (dev->numa_node != 0)
      return dev->numa_node > 0 ? dev->numa_node - 1 : dev->numa_node;

        PR libgomp/125877
        libgomp/
        * plugin/plugin-nvptx.c (nvptx_open_device): Initialize 'numa_node'.
