[PATCH RFC] net/sched: use real_num_tx_queues in dev_watchdog()

[Praveen Kumar Kannoju]

Currently dev_watchdog() loops through num_tx_queues[Number of TX queues
allocated at alloc_netdev_mq() time] instead of real_num_tx_queues
[Number of TX queues currently active in device] to detect transmit
queue time out. Make this efficient by using real_num_tx_queues.
