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

commit 958c0ba403cb6a693b54be2389f9ef53377fa259 upstream.

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.
