Fix verify_backlog start verification before finish writing

Due to recent fix for checking rand_seed in verify phase. In write phase,
the IO transaction will be logged before completing the actual data write.
If verify_backlog is enabled, verification may start before all data has
been written. This patch disable that fix if the verify_backlog is enabled.
