Fix detection of support for GPUDirect #45

The previous code would have considered the compute capablity of the last device. It makes more sense to require all GPUs to support GPUDirect in order to use it.

I expect this patch to be in the next public release of PSM2. Thanks to Jonas for submitting it.
