net_sched: Fix qdisc_notify()
Ben Pfaff reported a kernel oops and provided a test program to
reproduce it.
https://kerneltrap.org/mailarchive/linux-netdev/2010/5/21/6277805
tc_fill_qdisc() should not be called for builtin qdisc, or it
dereference a NULL pointer to get device ifindex.
Fix is to always use tc_qdisc_dump_ignore() before calling
tc_fill_qdisc().
