drm/nouveau: Don't disable polling in fallback mode

When a fan is controlled via linear fallback without cstate, we
shouldn't stop polling.  Otherwise it won't be adjusted again and
keeps running at an initial crazy pace.

Fixes: 800efb4c2857 ("drm/nouveau/drm/therm/fan: add a fallback if no fan control is specified in the vbios")
