sch_htb: remove from event queue in htb_parent_to_leaf()
There is lack of removing a class from the event queue while changing
from parent to leaf which can cause corruption of this rb tree. This
patch fixes a bug introduced by my patch: "sch_htb: turn intermediate
classes into leaves" commit: 160d5e10f87b1dc88fd9b84b31b1718e0fd76398.
Many thanks to Jan 'yanek' Bortl for finding a way to reproduce this
rare bug and narrowing the test case, which made possible proper
diagnosing.
This patch is recommended for all kernels starting from 2.6.20.
