CVE-2021-47659

While the check for format_count > 64 in __drmuniversalplaneinit() shouldn't be hit (it's a WARNON), in its current position it will then leak the plane->formattypes array and fail to call drmmodeobjectunregister() leaking the modeset identifier. Move it to the start of the function to avoid allocating those resources in the first place.
