adds log when gpuManager.start() failed
If gpuManager.start() returns error, there is no log.
We confused with scheduler do not schedule any pod(with gpu) to one node.
kubectl describe node xxx shows there is no gpu on that node, because the gpu driver do not work on that node, gpuManager.start() failed, but we can not see anything in log.
