[drm:i915_gem_object_unbind] *ERROR* Attempting to unbind pinned buffer

Hello,

I'm getting tons of this in /var/log/messages:
error: [drm:pid9:i915_gem_object_unbind] *ERROR* Attempting to unbind 
pinned buffer

As far I understand [1], this case is harmless and there is no point to 
print it with DRM_ERROR - DRM_DEBUG is sufficient. Can we please change 
it in our tree like it done in patch attached? Thanks.

PS. In Linux 3.8 [2] this check was changed by removing the warning 
altogether and just returning -EBUSY, so may be we can do just this to 
reduce the diff ;).
