net: sched: Fix qdisc_rate_table refcount leak when get tcf_block failed
The reference counting issue happens in one exception handling path of
cbq_change_class(). When failing to get tcf_block, the function forgets
to decrease the refcount of "rtab" increased by qdisc_put_rtab(),
causing a refcount leak.
Fix this issue by jumping to "failure" label when get tcf_block failed.
