[PATCH] drm/tests: fix drm_test_fb_xrgb8888_to_xrgb2101010 on big endian

[Dave Airlie]

From: Dave Airlie <airl...@redhat.com>

This test is failing for me on s390x and there is a report on the list from 
ppc64.

This aligns it with the argb test that doesn't fail.

Fixes: 15bda1f8de5d ("drm/tests: Add calls to drm_fb_blit() on supported format 
conversion tests")
