A recently fixed bug was caused by zone reset during asynchronous IOs
in-flight. The bug symptom was unaligned command error which was
observed using random write workload with libaio engine and block size
not a divisor of zone size. To confirm the bug fix and to prevent future
regression, add a test case which runs the workload.
