guest-diag: bpz6/invd - read the live arch/impl and test the WAR-ucode lookup
Run #5 named the failing hook: idx=3 FUN_005d7e70 ('membar_war_bug2022401')
returned 999; its only source is FUN_0035a4d0(0x13, dev+0xc50, dev+0xc54)
returning NULL or the ucode load failing. bpz6 reads the live device state
arch/impl at the failure and evaluates the lookup in-process, scanning
(arch,rev) pairs to show which WAR-ucode descriptors exist; invd.py is the
standalone same-probe for a parked cdt.
