media: ivtv: don't call s_stream(0) if not streaming
Recently a WARN_ON was added in v4l2-subdev.c to warn if s_stream was
called unnecessarily. The ivtv driver hits this once when it is loaded for
the first time. Add a bool to avoid this warning.
[hverkuil: added a comment for the sd_video_is_streaming field]
