Fix variable naming typos in community FluxControlNetFillInpaintPipeline (#12701)

- Fixed variable naming typos (maskkk -> mask_fill, mask_imagee -> mask_image_fill, masked_imagee -> masked_image_fill, masked_image_latentsss -> masked_latents_fill)

These changes improve code readability without affecting functionality.
