Renorm CFG is being also applied to seedvr model #1534

Expected Behavior

Generate images using both Renorm CFG and SeedVR without errors.

Actual Behavior

When trying to generate images with both Renorm CFG and SeedVR this error happens: AttributeError: 'NaDiT' object has no attribute 'in_channels'

It happens on line 31 of comfy_extras\nodes_lumina2.py

            in_channels = model.model.diffusion_model.in_channels

Looking at the generated workflow, RenormCFG is also being applied to the SeedVR model.

Bypassing this second RenormCFG node generated the image with no error.

Steps to Reproduce

• set Renorm CFG to any value > 0
• enable SeedVR and select a SeedVR model
• Generate
