Cong Wang 76c4c22c24 net_sched: hfsc: Fix a potential UAF in hfsc_dequeue() too 
[ Upstream commit 6ccbda44e2cc3d26fd22af54c650d6d5d801addf ]

Similarly to the previous patch, we need to safe guard hfsc_dequeue()
too. But for this one, we don't have a reliable reproducer.

Fixes: 1da177e4c3 ("Linux-2.6.12-rc2")
