HunyuanVideoImageToVideoPipeline memory leak

### Describe the bug

`RuntimeError: Invalid buffer size: 635.13 GB` on Apple Silicon with mps, when the readme claims 60GB. Smaller res possible but still with 10x the memory claimed. What's going on here? Is it leaking memory?

Reproducible from boilerplate example code:

```import torch
from diffusers import HunyuanVideoImageToVideoPipeline, HunyuanVideoTransformer3DModel
from diffusers.utils import load_image, export_to_video

# Available checkpoints: "hunyuanvideo-community/HunyuanVideo-I2V" and "hunyuanvideo-community/HunyuanVideo-I2V-33ch"
model_id = "hunyuanvideo-community/HunyuanVideo-I2V"
transformer = HunyuanVideoTransformer3DModel.from_pretrained(
model_id, subfolder="transformer", torch_dtype=torch.bfloat16
)
pipe = HunyuanVideoImageToVideoPipeline.from_pretrained(
model_id, transformer=transformer, torch_dtype=torch.float16
)
pipe.vae.enable_tiling()
pipe.to("mps")

prompt = "A man with short gray hair plays a red electric guitar."
image = load_image(
"https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/diffusers/guitar-man.png"
)

output = pipe(image=image, prompt=prompt).frames[0]
export_to_video(output, "output.mp4", fps=15)
```
