Use the generic positive-int-or-None validator for max_total_rows

The dbapi connection modules validated `max_total_rows` through a
specialised helper that the client package no longer ships. Switch
to the shared `_validate_positive_int_or_none` import so both
packages share one validator; error wording is byte-identical when
the helper is given `name="max_total_rows"`.
