Bug in platform detection in APP SDK samples

There's a bug in the validation of having a GPU in CLCommandArgs::validatePlatformAndDeviceOptions(). This results in the message "GPU not found. Falling back to CPU device" when running the program.

The bug is in setting 'gpu = false' when a GPU device isn't found (line 1383 of CLUtil.hpp). If there's a platform with no GPU, gpu will be set to false even though there's another platform that does have a GPU. Common example: both AMD and Intel OpenCL drivers are installed.

This can be solved by inverting the logic: start with 'gpu = false', then set 'gpu = true' and break when a GPU platform is found.

Thanks for pointing out the code section and your suggestion. I've already passed it to sdk team and hope, it'll be fixed in next release.

Regards,
