    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.
