[PATCH 1/2] drm/tests: Fix endian warning

[José Expósito]

When compiling with sparse enabled, this warning is thrown:

  warning: incorrect type in argument 2 (different base types)
     expected restricted __le32 const [usertype] *buf
     got unsigned int [usertype] *[assigned] buf

Add a cast to fix it.

Fixes: 453114319699 ("drm/format-helper: Add KUnit tests for drm_fb_xrgb8888_to_xrgb2101010()")
