Subject: [PATCH] drm/i915: hush check crtc state
 
This is _by far_ the most common backtrace for i915 on retrace.fp.o, and
it's mostly useless noise.  There's not enough context when it's generated
to know if something actually went wrong.  Downgrade the message to
KMS debugging so we can still get it if we want it.
