The lockdep_hardirqs_disabled() check in __sev_get/put_ghcb() was problematic, because these functions are called also when no state is set up yet. More specifically it is called from __sev_es_nmi_complete(), which is called at the very beginning of do_nmi(), before the NMI handler entered NMI mode. So this triggered a warning in the NMI test-suite when booting up, I replaced these checks with a WARN_ON(!irqs_disabled()) and also removed the BUG_ON()s. With that it boots fine and without SEV-ES related warnings.
