[PATCH v2/RESEND] drm: nouveau: Fix build warning seen if HWMON is undefined

[Guenter Roeck]

Fix:

nouveau_pm.c: In function ?nouveau_hwmon_init?:
nouveau_pm.c:703:24: warning: unused variable ?therm? [-Wunused-variable]

Introduced by commit 095f979a (drm/nouveau/pm: fix build with HWMON off) which
fixed a build error but introduced a build warning.
