Kaitao Cheng 5ab4bb7b40 kernel/trace: Fix do not unregister tracepoints when register sched_migrate_task fail 
commit 50f9ad607e upstream.

In the function, if register_trace_sched_migrate_task() returns error,
sched_switch/sched_wakeup_new/sched_wakeup won't unregister. That is
why fail_deprobe_sched_switch was added.
