net: Fix build failure with 'make mandocs'.
The function header comments have to go with the functions they are documenting, or things go horribly wrong when we try to process them with the docbook tools.

1649 * dev_queue_xmit - transmit a buffer
1650 * @skb: buffer to transmit
1651 *
1652 * Queue a buffer for transmission to a network device. The caller must
1653 * have set the device and priority and built the buffer before calling
1654 * this function. The function can be called from an interrupt.
1655 *
1656 * A negative errno code is returned on a failure. A success does not
1657 * guarantee the frame will be transmitted as it may be dropped due
1658 * to congestion or traffic shaping.
1659 *
1660 * -----------------------------------------------------------------------------------
1661 * I notice this method can also return errors from the queue disciplines,
1662 * including NET_XMIT_DROP, which is a positive value. So, errors can also
1663 * be positive.
1664 *
1665 * Regardless of the return value, the skb is consumed, so it is currently
1666 * difficult to retry a send to this method. (You can bump the ref count
1667 * before sending to hold a reference for retry if you are careful.)
1668 *
1669 * When calling this method, interrupts MUST be enabled. This is because
1670 * the BH enable code must have IRQs enabled so that it will not deadlock.
