clGetDeviceIDs 'num_devices' output parameter is described as:
> num_devices returns the number of OpenCL devices available that match
device_type.
but the _test_events
out_of_order_event_waitlist_multi_queue_multi_device_ test expects that
after calling:
`clGetDeviceIDs(platform, CL_DEVICE_TYPE_ALL, 2, two_device_ids,
&number_returned);`
the content of number_returned needs to be 2, but it should be valid to
return a larger number.
