show() must not use snprintf() when formatting the value to be returned to user space.

Fix the following coccicheck warning: drivers/gpu/drm/nouveau/nouveau_hwmon.c:43:8-16: WARNING: use scnprintf or sprintf. drivers/gpu/drm/nouveau/nouveau_hwmon.c:57:8-16: WARNING: use scnprintf or sprintf. drivers/gpu/drm/nouveau/nouveau_hwmon.c:90:8-16: WARNING: use scnprintf or sprintf.

Use sysfs_emit instead of scnprintf or sprintf makes more sense.
