Hans Verkuil 995f5fefb0 V4L/DVB: media-spec: Fix documentation mistakes regarding I/O streaming ...

The media spec contains several errors in the description of the
I/O streaming ioctls, in particular with respect to the userptr
I/O method.

The most important change is that you really need to set count
and index in v4l2_requestbuffer and v4l2_buffer when dealing with
user pointer streaming.
