remove verify in rand write test

See the fio bug io reports verify: bad header rand_seed when using zoned random distribution
Sitsofe recommend steering clear of randrw verification jobs - they are notorious for being difficult.
The date verify is important,but not run well at rand write test
I used ezfio and found that bug below:
