zbd: do not reset extra zones in open conditions

The commit 954217b ("zbd: Initialize open zones list referring zone
status at fio start") introduced zone resets for zones in open condition
which exceeds the limit of max_open_zones. However, this zone reset may
break data in the zones even when fio does no write to them. Avoid the
zone reset and report it as an error.
