commit_lock_file(): die() if called for unlocked lockfile object
It was previously a bug to call commit_lock_file() with a lock_file object that was not active (an illegal access would happen within the function). It was presumably never done, but this would be an easy programming error to overlook. So before continuing, do a consistency check that the lock_file object really is locked.
