scsi: message: fusion: Use sysfs_emit in show function callsbacks

Commit Message

Deepak R Varma Dec. 25, 2022, 8:44 a.m. UTC

According to Documentation/filesystems/sysfs.rst, the show() callback
function of kobject attributes should strictly use sysfs_emit() instead
of sprintf() family functions. So, make this change.
Issue identified using the coccinelle device_attr_show.cocci script.
