Subject: [PATCH] test/nvmf: enable fio verify_backlog option

Using time_based tasks with do_verify=1 and rw=write
results in verification not being run. Basically
writes consume all run time and there's no time
left for verify:

fio: verification read phase will never start
because write phase uses all of runtime

Using verify_backlog we ask fio to verify after every
N blocks written.
