net: Clean up explicit ->tx_queue references in link watch.
First, we add a qdisc_tx_changing() helper which returns true if the qdisc attachment is in transition. Second, we remove an assertion warning which is of limited value and is hard to express precisely in a multiqueue environment. Signed-off-by: David S. Miller <davem@davemloft.net>
