Ricardo Ribalda f956035ce7 [media] vb2: Return 0 when streamon and streamoff are already on/off 
According to the doc:
If VIDIOC_STREAMON is called when streaming is already in progress,
or if VIDIOC_STREAMOFF is called when streaming is already stopped,
then the ioctl does nothing and 0 is returned.
The current implementation was returning -EINVAL instead.
