tracing: Properly process error handling in event_hist_trigger_parse()

Memory allocated with trigger_data_alloc() requires trigger_data_free()
for proper cleanup.

Replace kfree() with trigger_data_free() to fix this.

Found via static analysis and code review.

This isn't a real bug due to the current code basically being an open
coded version of trigger_data_free() without the synchronization. The
synchronization isn't needed as this is the error path of creation and
there's nothing to synchronize against yet. Replace the kfree() to be
consistent with the allocation.
