You need to remove for_each_valid_output_on_pipe() logic from 
run_test(), since we already doing here the same.

We are no where using this "data.output".

Actually, run_test() is iterating for_each_pipe_with_valid_output() to 
get valid pipe/connector combination.

If you want to create dynamic subtests with pipe/connector config, you 
need to iterate for_each_pipe_with_valid_output() before calling 
igt_dynamic() and remove the same logic from run_test().
