Sakari Ailus 4ebddb7c17 media: entity: Add lockdep check to media graph walk
It was always assumed that walking the media graph would require holding
the media_device graph_mutex but this was not documented nor checked for.

Add a lockdep check to graph walk init and iter, and document the need for
acquiring the graph_mutex.
