Fix autovacuum log output heap truncation issue. The percentage of blocks from the table value reported by autovacuum log output (following commit 5100010ee4d) should never exceed 100% because it describes the state of the table back when lazy_vacuum() was called. The value could nevertheless exceed 100% in the event of heap relation truncation. We failed to compensate for how truncation affects rel_pages.
Fix the faulty accounting by using the original rel_pages value instead of the current/final rel_pages value.
