s390/lcs: Convert sysfs sprintf to sysfs_emit

Browse Source 
Following the advice of the Documentation/filesystems/sysfs.rst.
All sysfs related show()-functions should only use sysfs_emit() or
sysfs_emit_at() when formatting the value to be returned to user space.

While at it, follow Linux kernel coding style and unify indentation
