drm/i915: Skip stolen region initialisation if none is reserved
Paulo reported that if he set the amount of reserved memory to 0, then we emitted a warning about a conflict before disabling our use of stolen memory. This was introduced with commit eaba1b8f3379b5d100bd146b9a41d28348bdfd09 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Jul 4 12:28:35 2013 +0100 drm/i915: Verify that our stolen memory doesn't conflict and is simply fixed by checking for a no reservation first.
