staging: r8188eu: remove comments about endpoint mapping

Remove the comments in two_out_pipe and three_out_pipe that show the
mappings. They simply repeat the settings in the code and provide no
additional information. Keep the info which RtOutPipe is high, normal
or low.

Without the removed comments, it'll be easier to summarize and reorganize
the code.
