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.
