    r8152: fix the list rx_done may be used without initialization

    The list rx_done would be initialized when the linking on occurs.
    Therefore, if a napi is scheduled without any linking on before,
    the following kernel panic would happen.

        BUG: unable to handle kernel NULL pointer dereference at 000000000000008
