Subject: tuntap: restore default qdisc

From: Jason Wang <[email protected]>

[ Upstream commit 016adb7260f481168c03e09f785184d6d5278894 ]

After commit f84bb1eac027 ("net: fix IFF_NO_QUEUE for drivers using alloc_netdev"), default qdisc was changed to noqueue because tuntap does not set tx_queue_len during .setup(). This patch restores default qdisc by setting tx_queue_len in tun_setup().
