Describe the bug

This commit on main https://github.com/huggingface/diffusers/commit/14a1b86fc7de53ff1dbf803f616cbb16ad530e45 seems to have broke FluxMultiControlNetModel. Reverting this commit fixes the issue on line pipeline_flux_controlnet.py:844

Referencing this issue: https://huggingface.co/Shakker-Labs/FLUX.1-dev-ControlNet-Union-Pro/discussions/20

Reproduction

base_model = "/archive/me_flux_shallow/FLUX.1-dev"
controlnet_model_union = 'Shakker-Labs/FLUX.1-dev-ControlNet-Union-Pro'

controlnet_union = FluxControlNetModel.from_pretrained(controlnet_model_union, torch_dtype=torch.bfloat16)
controlnet = FluxMultiControlNetModel([controlnet_union])

pipe = FluxControlNetPipeline.from_pretrained(base_model, controlnet=controlnet, torch_dtype=torch.bfloat16)
pipe.to("cuda:0")

prompt = 'A bohemian-style female travel blogger with sun-kissed skin and messy beach waves.'
control_image_depth = load_image("/home/me/repos/flux_control_net/assets_depth.jpg")
control_mode_depth = 2

control_image_canny = load_image("/home/me/repos/flux_control_net/assets_canny.jpg")
control_mode_canny = 0

width, height = control_image_depth.size

image = pipe(
    prompt, 
    control_image=[control_image_depth, control_image_canny],
    control_mode=[control_mode_depth, control_mode_canny],
    width=width,
    height=height,
    controlnet_conditioning_scale=0.6,
    num_inference_steps=24, 
    guidance_scale=3.5,
    generator=torch.manual_seed(42),
).images[0]
