    scripts/kernel-doc: Do not track section counter across processed files
    
    [ Upstream commit be9264110e4e874622d588a75daf930539fdf6ea ]
    
    The section counter tracks how many sections of kernel-doc were added.
    The only real use of the counter value is to check if anything was
    actually supposed to be output and give a warning is nothing is
    available.
    
    The current logic of remembering the initial value and then resetting
    the value then when processing each file means that if a file has the
    same number of sections as the previously processed one, a warning is
    incorrectly given.
