kernel/trace: Fix do not unregister tracepoints when register sched_migrate_task fail
commit 50f9ad607ea891a9308e67b81f774c71736d1098 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.
