    HID: core: fix reporting of raw events
    
    hdrw->raw event can return three different return value types:
    
    - ret < 0   indicates that the hdrv driver found an error while parsing
    - ret == 0  indicates no error has been encountered, and the driver has
                processed the report
    - ret > 0   indicates that there was no parsing error, and the driver hasn't
                processed the event.
    
    Calling hid_report_raw_event() has to be called appropriately so that it
    reflects what has been done by ->raw_event() callback, otherwise we might
    updates of the in-kernel structure are lost upon arrival of the report, 
which
    is wrong.
