[PATCH 6/7] drm/i915: only check for unclaimed registers if drm_debug

[Paulo Zanoni <przanoni@gmail.com>]

From: Paulo Zanoni <paulo.r.zanoni@intel.com>

This is a debug feature that may pollute dmesg and scare users, so
leave it for the debug mode only. We usually ask for bug reporters to
use the debug flags, so we will still have the opportunity to catch a
lot of errors on users' machines.
