The SCCB must be checked for a sufficient length before it is filled

This is not a fix AFAIKs.
sclp_service_call()/sclp_service_call_protected() always supplies a full
SCCB of exactly 4k size.
Right. This is more-or-less a preparation patch for the extended-length
SCCB stuff which allows an SCCB > 4k.
The Linux kernel always provides a 4k SSCB today, so this patch
more-or-less makes the code AR compliant.
