Revised CCheckFreeGpus.cpp:
1) When -UseGpus is not present in command line, do not check. This
means all specified GPUs following -GPU will be used.
2) When -UseGpus specifies the same as or more GPUs than -Gpu provides,
do not check. This means all specified GPUs following -GPU will be used.
3) This is based on Github user request.
