[PATCH] platform/x86: use sysfs_emit() to instead of scnprintf()

[<ye.xingchen@xxxxxxxxxx>]

From: ye xingchen <ye.xingchen@xxxxxxxxxx>

Follow the advice of the Documentation/filesystems/sysfs.rst and show()
should only use sysfs_emit() or sysfs_emit_at() when formatting the
value to be returned to user space.
