Commit ae219872834a ("media: mc: entity: Rewrite
media_pipeline_start()") incorrectly referred to entity instead of pad
in a comment, and forgot to update a second comment accordingly when
moving the pipe from entity to pad. Furthermore, it didn't properly
reflow the documentation text it updated.
Fix those small issues.

The pipeline pointer must be identical for all nested calls to the function.
