Chen Zhou 92fd356514 s390: use scnprintf() in sys_##_prefix##_##_name##_show ...

snprintf() returns the number of bytes that would be written,
which may be greater than the the actual length to be written.

show() methods should return the number of bytes printed into the
buffer. This is the return value of scnprintf().
