[Bug Fix] Segfaults/UB when deleting images with 2 or more instances

[pajotg]

When trying to delete a image with 2 or more instances it would only delete the first draw queue element, causing segfaults and other weird things when trying to render the leftover draw queue the next frame

The simplest way to reproduce this segfault would be to compile & run this code:

void hook(void* param)
{
	mlx_t *mlx = param;

	mlx_image_t* g_img = mlx_new_image(mlx, 128, 128);
	mlx_image_to_window(mlx, g_img, 0, 0);
	mlx_image_to_window(mlx, g_img, 0, 0);
	mlx_delete_image(mlx, g_img);
}

int main()
{
	mlx_t* mlx = mlx_init(512, 512, "Segfault Test", true);

	mlx_loop_hook(mlx, &hook, mlx);
	mlx_loop(mlx);
}

Apparently my editor automatically removed spaces at the end of lines, so i guess thats in there too
