    net: hns3: revert to old channel when setting new channel num fail

    After setting new channel num, it needs free old ring memory and
    allocate new ring memory. If there is no enough memory and allocate
    new ring memory fail, the ring may initialize fail. To make sure
    the network interface can work normally, driver should revert the
    channel to the old configuration.
