Alexander Motin fa7b2390d4 Do not report bytes skipped by scan as issued. ... Scan process may skip blocks based on their birth time, DVA, etc. Traditionally those blocks were accounted as issued, that caused reporting of hugely over-inflated numbers, having nothing to do with actual disk I/O. This change utilizes never used field in struct dsl_scan_phys to account such skipped bytes, allowing to report how much data were actually scrubbed/resilvered and what is the actual I/O speed. While formally it is an on-disk format change, it should be compatible both ways, so should not need a feature flag. This should partially address the same issue as c85ac731a0, but from a different perspective, complementing it.
