lockstat: Fix min, max times in /proc/lock_stats
Fix min, max times in /proc/lock_stats (1) When collecting lock hold and wait times, if the current minimum time is zero, it will be replaced by the next time. (2) When aggregating minimum and maximum lock hold and wait times accross cpus, the values are added, instead of selecting the minimum and maximum.
