Add test cases to reproduce scenarios fixed recently [1] where
multiqueue and taprio forced their children into enqueueing an skb to
gso_skb (during peek), but failed to dequeue from gso_skb because they
called the child's dequeue callback directly. This causes a desync in the
child's qlen/backlog and results in an eventual null-ptr-deref (with a
qfq or dualpi2 child).
