fio: fix s390 nop

When trying to run rate limited fio runs we encountered that the current
definition of a nop uses a privileged instruction which is not even a nop,
but a yield call to the hipervisor.
That leads to a SIGILL as it is privileged.

To solve that issue replace it with a nop, the assembler will take care
of it (likely to become a BCR 0,0)
