    kernel - Attempt to fix illegal xfer buffer in ulpt*
    
    Use usbd_alloc_buffer() to allocate the dummy input buffer for reading
    status from the printer instead of passing a (possibly badly misaligned or
    illegally addressed) buffer embedded in the softc.
    
    This appears to fix numerous issues with ulpt on 64-bit systems.
