sch_sfq: fix sfq_enqueue()

commit 8efa88540635 (sch_sfq: avoid giving spurious NET_XMIT_CN signals)
forgot to call qdisc_tree_decrease_qlen() to signal upper levels that a
packet (from another flow) was dropped, leading to various problems.

With help from Michal Soltys and Michal Pokrywka, who did a bisection.
