Block statistics calculation during scrub I/O issue in case of sorted scrub accounted ditto blocks several times. Embedded blocks on other side were not accounted at all. This change moves the accounting from issue to scan stage, that fixes both problems and also allows to avoid pool-wide locking and the lock contention it created. Since this statistics is quite specific and is not even exposed now anywhere, disable its calculation by default to not waste CPU time.
