Budimir Markovic 5293f466d4 net/sched: sch_hfsc: Ensure inner classes have fsc curve 
[ Upstream commit b3d26c5702 ]

HFSC assumes that inner classes have an fsc curve, but it is currently
possible for classes without an fsc curve to become parents. This leads
to bugs including a use-after-free.

Don't allow non-root classes without HFSC_FSC to become parents.

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