[S390] qdio: use proper QEBSM operand for SIGA-R and SIGA-S

Browse source

If QIOASSIST is enabled for a qdio device the SIGA instruction requires
a modified function code. This function code modifier was missing for
SIGA-R and SIGA-S which can lead to a kernel panic caused by an
operand exception.
