test/vhost: Fix write with verification. 



Change is needed because fio job (trim_write_read)
submits unmap first and then write,
but sometimes write finishes before unmap.
It casues that write fails with verification.

Nvm Express 1.3:
"The controller fetches SQ entries in order from the Submission Queue,
however, it may then execute those commands in any order. "
