[Bug] Model quantization yields 0kb file for "zimage turbo" model

[pintubiru]

I am encountering an issue when trying to quantize zimage turbo model. The process appears to run normally, but the resulting model file in the output directory has a size of 0kb and is unusable. Other models like SDXL seem to quantize correctlyl.

I haven't tried converting zimage-turbo but I think the conversion should work the same way as in SDXL.
I'll take a look at it.
