The walk implementation of most tc cls modules is basically the same.
That is, the values of count and skip are checked first. If count is
greater than or equal to skip, the registered fn function is executed.
Otherwise, increase the value of count. So the code can be refactored.
Then use helper function to replace the code of each cls module in
alphabetical order.
The walk function is invoked during dump. Therefore, test cases related
to the tdc filter need to be added.
Last, thanks to Jamal, Victor and Wang for their review.
