[PATCH next] drm/tests: Fix a test in drm_test_check_valid_clones()

[Dan Carpenter <dan.carpenter@xxxxxxxxxx>]

The drm_atomic_get_crtc_state() function returns error pointers and not
NULL.  Update the check to check for error pointers as well as NULL.

Fixes: 88849f24e2ab ("drm/tests: Add test for drm_atomic_helper_check_modeset()")
