due to hardware limitations we cannot rely on the OESC error code
before the hardware parsed the initial huffman tree. For this case
we have to add a branch to the EOF handling. we return an errorcode 2
(invalid data) if we where still in the initial phase (bytes_out == 0).
Otherwise we continue with the default EOF handling.
