Summary of the bug:
How to reproduce:

ffmpeg -v verbose -init_hw_device vulkan=vul -filter_hw_device vul -i input1080p.264 -vf "hwupload=extra_hw_frames=16,scale_vulkan=1920:1080,hwdownload,format=yuv420p" -f rawvideo output.yuv

built on ffmpeg master
GPU: 2080Ti

This command reports a segmentation fault at

I think the problem is that when queue_count is greater than 1, pl->descriptor_sets_num will be greater than pl->desc_layout and vkAllocateDescriptorSets will cause error.
