drm/i915: Downgrade Gen9 Plane WM latency error
commit 86c1c87d0e6241cbe35bd52badfc84b154e1b959 upstream.
According to intel_read_wm_latency() it is perfectly legal for one WM
and all subsequent levels to be 0 (and the deeper powersaving states
disabled), so don't shout *ERROR*, over and over again.
