CurOp uses on Locker::getLockInfo in order to obtain cumulative wait time via getCumulativeWaitTimeMicros

This seems to represent around 1us cost for find by id queries. It likely could be reduced to 0.2us by avoiding copying and manipulating LockStats, but instead extracting aggregate time from atomic stats directly as only a subset of stats is needed for this computation. This should result in approx 1% improvemement for find by id queries.
