drm/i915: redefine WARN_ON_ONCE to include the condition
Same as commit c883ef1b Author: Mika Kuoppala <miku@iki.fi> Date: Tue Oct 28 17:32:30 2014 +0200 drm/i915: Redefine WARN_ON to include the condition but for WARN_ON_ONCE. Since the kernel WARN_ON_ONCE actually picks up *our* version of WARN_ON, we end up with messages like [ 838.285319] WARN_ON(!__warned) which are not that helpful.
