perf lock: Carefully combine lock stats for discarded entries
Stats from discarded entries should be omitted.
But a lock class may have both good and bad entries.
If the first entry was bad, we can zero-fill the stats and only add good
stats if any.
The entry can remove the discard state if it finds a good entry later.
