Subject: [PATCH 05/18] s390x/sclp.c: remove unneeded label in

O-Subject: [RHEL-8.4.0 qemu-kvm PATCH v2 01/12] s390x/sclp.c: remove unneeded label in sclp_service_call()
Bugzilla: 1798506

'out' label can be replaced by 'return' with the appropriate
value. The 'r' integer, which is used solely to set the
return value for this label, can also be removed.
