tracing/profile: fix profile_disable vs module_unload
If the correspoding module is unloaded before ftrace_profile_disable()
is called, event->profile_disable() won't be called, which can
cause oops:
# insmod trace-events-sample.ko
# perf record -f -a -e sample:foo_bar sleep 3 &
# sleep 1
# rmmod trace_events_sample
# insmod trace-events-sample.ko
OOPS!
