audio: Return ENODATA when position is failed to be retreived

out_get_presentation_position returns ENOPERM if it is called
when underlying pcm stream is not opened. This is resulting
in an error log on the client side.

ENODATA is more appropriate in this case as stream is yet
to be opened and is not an error scenario.
