scsi: pm8001: Use sysfs_emit() in show function callbacks

According to Documentation/filesystems/sysfs.rst, the show() callback
function of kobject attributes should use sysfs_emit() instead of the
sprintf() family of functions.

Issue identified using the coccinelle device_attr_show.cocci script.
