[S390] qdio: remove enhanced SIGA
HiperSocket devices only use one SBAL per qdio call without the enhanced SIGA feature. Since that feature is currently not used remove it from the qdio code so the compiler can generate better code for the HiperSocket outbound path. While at it mark the SIGA error conditions as unlikely. Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
