Benchmark mad crash on Jetson Nano

[tpoisonooo]

mad_throughput crashed on Jetson Nano and throw VK_ERROR_DEVICE_LOST.

This is call chain:

mad_throughput_main.cc:189  --->   GetDeviceBufferViaStagingBuffer -->  vulkan_buffer_util.cc:67 ---->  QueueSubmitAndWait ---> crash

No nullptr or bad variable found.

I have tried to fix it by validation layer, but Jetson Nano does not support it ... 0 == layerCount

VK_ERROR_DEVICE_LOST is an indication that the workload is taking too much time to complete on the GPU (given we have a weak GPU on Jetson Nano I think). You can try to reduce the amount of workload to see if it helps.
