[PATCH 1/2] drm/i915: Clear unused fields of mode for framebuffer creation

drm/i915: Check the framebuffer offset

(and friends), it became especially prudent to make sure that the
additional fields inside the mode were cleared before attempting to
create a framebuffer. In particular, the fb created for load detection
failed to do so and hence failed.
