scsi: scsi_transport_sas: Use sysfs_emit in show function callsbacks

Commit Message

Deepak R Varma Dec. 23, 2022, 8:07 p.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.

Issue identified using the coccinelle device_attr_show.cocci script.
