s390/sclp: read sccb from mem based on provided length
The header contained within the SCCB passed to the SCLP service call contains the actual length of the SCCB. Instead of allocating a static 4K size for the work sccb, let's allow for a variable size determined by the value in the header. The proper checks are already in place to ensure the SCCB length is sufficent to store a full response and that the length does not cross any explicitly-set boundaries.
