SD1.5 - pipeline_controlnet_img2img and pipeline_controlnet_inpaint are mixing variables "image" and "control_image"

### Describe the bug

"image" is used in pipeline_controlnet for a list of controlnet images.
"control_image" is used in pipeline_controlnet_img2img and pipeline_controlnet_inpaint for a list of controlnet images.
img2img and inpaint are missing "control_image" in check_inputs function causing an error

The img2img and inpaint check_inputs function is checking against "image" twice instead of "image" and "control_image".
this section from both files is for the "control_image" list but is checking against "image"

if not isinstance(image, list):
raise TypeError("For multiple controlnets: `image` must be type `list`")

# When `image` is a nested list:
# (e.g. [[canny_image_1, pose_image_1], [canny_image_2, pose_image_2]])
elif any(isinstance(i, list) for i in image):
raise ValueError("A single batch of multiple conditionings are supported at the moment.")
elif len(image) != len(self.controlnet.nets):
raise ValueError(
f"For multiple controlnets: `image` must have the same length as the number of controlnets, but got {len(image)} images and {len(self.controlnet.nets)} ControlNets."
)

for image_ in image:
self.check_image(image_, prompt, prompt_embeds)
###
quick fix - add "control_image" to def check_inputs and self.check_inputs and replace the above with the following
###
if not isinstance(control_image, list):
raise TypeError("For multiple controlnets: `control_image` must be type `list`")

# When `control_image` is a nested list:
# (e.g. [[canny_image_1, pose_image_1], [canny_image_2, pose_image_2]])
elif any(isinstance(i, list) for i in control_image):
raise ValueError("A single batch of multiple conditionings are supported at the moment.")
elif len(control_image) != len(self.controlnet.nets):
raise ValueError(
f"For multiple controlnets: `control_image` must have the same length as the number of controlnets, but got {len(control_image)} images and {len(self.controlnet.nets)} ControlNets."
)

for image_ in control_image:
self.check_image(image_, prompt, prompt_embeds)

### Who can help?

_No response_

Start with the check_inputs definitions and calls in pipeline_controlnet_img2img and pipeline_controlnet_inpaint. Compare the multiple-ControlNet validation with pipeline_controlnet, then verify that both pipelines validate control_image consistently and that the existing pipeline tests pass; done means the checks no longer inspect image twice.
