Fix a bug in the lock tracking code that was discovered by mmichelson.  The issue
is that if the lock history array was full, then the functions to mark a lock as
acquired or not would adjust the stats for whatever lock is at the end of the array,
which may not be itself.  So, do a sanity check to make sure that we're updating
lock info for the proper lock.

(This explains the bizarre stats on lock #63 in BE-396, thanks Mark!)
