Collin Walling 0260b97824 s390/sclp: check sccb len before filling in data 
The SCCB must be checked for a sufficient length before it is filled
with any data. If the length is insufficient, then the SCLP command
is suppressed and the proper response code is set in the SCCB header.

While we're at it, let's cleanup the length check by placing the
calculation inside a macro.
