Create 3 test cases:
- Verify fq_codel won't mistakenly deactivate QFQ parent class during peek
- Verify codel won't mistakenly deactivate QFQ parent class during peek
- Verify dualpi2 won't mistakenly deactivate QFQ parent class during peek
Verify that these 3 qdiscs (fq_codel, codel, dualpi2) will not call
qdisc_tree_reduce_backlog with an incorrect qlen (0) during peek and
mistakenly deactivate a parent class.
