[PATCH] scsi: hisi_sas: use sysfs_emit() in v3 hw show() functions

[Khaled Elnaggar <khaledelnaggarlinux@gmail.com>]

Replace scnprintf() with sysfs_emit() in several sysfs show()
callbacks in hisi_sas_v3_hw.c. This is recommended in
Documentation/filesystems/sysfs.rst for formatting values returned to
userspace.
