Issue with Weighting in sd15_face_id_portrait

[hben35096]

It seems there is an issue with the weighting of the sd15_face_id_portrait model. It appears that the weights are being accumulated based on the number of images.

Test 1:

Inputting 1 image with a weight of 0.5 yields a relatively normal result.

Test 2:

Inputting 4 images with a weight of 0.5 produces disturbing results.

Test 3:

Inputting 4 images with a weight adjusted to 0.5 divided by 4, approximately 0.12, yields a relatively normal result again.

Test 4:

Inputting 6 images with a weight of 0.5 produces disturbing results.

https://github.com/Mikubill/sd-webui-controlnet/pull/2539 will allow you use weight = 1, but there are still some subtle bugs.
