[PATCH] scsi: hptiop: Use sysfs_emit in show function callback

[Deepak R Varma]

According to Documentation/filesystems/sysfs.rst, show() callback
function should only use sysfs_emit() or sysfs_emit_at() instead
of sprint() family functions when formatting the device attribute
values to be returned to user space.
Issue identified using the device_attr_show.cocci Coccinelle script.
