Description (last modified by wenbin,chen)

Summary of the bug:
How to reproduce:

ffmpeg -init_hw_device vulkan=vul:0 -filter_hw_device vul -i 1080P.264 -vf "hwupload=extra_hw_frames=16,scale_vulkan=w=1920:h=1080" -f null -

Error occurs at ​https://github.com/FFmpeg/FFmpeg/blob/2fac1e370c9cf48b2e9d4a7f2c0d7236017f9bbe/libavutil/hwcontext_vulkan.c#L1018
The CreateCommandPool function is not loaded, so the function pointer is NULL.

I think the code in ​https://github.com/FFmpeg/FFmpeg/blob/2fac1e370c9cf48b2e9d4a7f2c0d7236017f9bbe/libavutil/hwcontext_vulkan.c#L1352 should be changed to 

err = load_functions(ctx, 1, 1);
