hwmon: Use sysfs_emit in show function callbacks

Browse source

Use sysfs_emit() over sprintf() to prevent potential overflows. In
hwmon_attr_show() that is totally impossible but looking other places
many still use sysfs_emit().

Also according Documentation/filesystems/sysfs.rst code should use
sysfs_emit().
