ppp: set qdisc_tx_busylock to avoid LOCKDEP splat
If a qdisc is installed on a ppp device, its possible to get
a lockdep splat under stress, because nested dev_queue_xmit() can
lock busylock a second time (on a different device, so its a false
positive)
Avoid this problem using a distinct lock_class_key for ppp
devices.
