Tom de Vries 738c56d410 [nvptx, libgomp] Fix memleak in GOMP_OFFLOAD_fini_device 
I wrote a test-case:
...
int
main (void)
{
  for (unsigned i = 0; i < 128; ++i)
    {
      acc_init (acc_device_nvidia);
      acc_shutdown (acc_device_nvidia);
    }

  return 0;
}
...
and ran it under valgrind.  The only leak location reported with a frequency
of 128, was the allocation of ptx_devices in nvptx_init.

Fix this by freeing ptx_devices in GOMP_OFFLOAD_fini_device, once
instantiated_devices drops to 0.

	* plugin/plugin-nvptx.c (GOMP_OFFLOAD_fini_device): Free ptx_devices
