DeepStream nvinfer input tensor contains incorrect image

[fanzh]

1. yes, there is only one CUDA stream nvinfer->convertStream, which will be passed to NvBufSurfTransform, to user it is synchronous, using cudaMemset2DAsync GPU will start processing without waiting all data is received, compared cudaMemset2D it is an “async” mode. please compare deepstream 5.1 and 6.1, there is no sync operation.
   2 . about "I’ve dumped input tensors of License Plate Detector with raw-output-file-write=1 and converted them to images. ", don’t know how you did that, we use DeepStream SDK FAQ - #9 by mchi section 3 to dump input tensor.
