JaxbDataFormat.unmarshal should use passed Exchange when converting given InputStream into XMLStreamReader

From JaxbDataFormat.unmarshal:

...
XMLStreamReader xmlReader;
  if (needFiltering(exchange)) {
    xmlReader = typeConverter.convertTo(XMLStreamReader.class, createNonXmlFilterReader(exchange, stream));
  } else {
    xmlReader = typeConverter.convertTo(XMLStreamReader.class, stream);
  }
...

The passed Exchange is not used during the convertTo invocation. Any other invocation in the JaxbDataFormat class passes the given Exchange object.
Passing the Exchange object gives a chance to the type converter to configure itself before converting.
