[PATCH 3.13 081/105] drm/ast: Fix HW cursor image

From: Benjamin Herrenschmidt <benh@kernel.crashing.org>

commit 1e99cfa8de0f0879091e33cd65fd60418d006ad9 upstream.

The translation from the X driver to the KMS one typo'ed a couple
of array indices, causing the HW cursor to look weird (blocky with
leaking edge colors). This fixes it.
