tracing: Move event_trigger_unlock_commit{_regs}() to local header
The functions event_trigger_unlock_commit() and event_trigger_unlock_commit_regs() are no longer used outside the tracing system. Move them out of the generic headers and into the local one. Along with __event_trigger_test_discard() that is only used by them. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

- * It also checks if the event should be discarded or not.
- * It is to be discarded if the event is soft disabled and the

- * filter is active and this event did not match the filters.
- *
- * Returns true if the event is discarded, false otherwise.
