I see the similar issue with non SEV guest with my simple patch below. Guest will reboot as soon as it tries to enable the key.
Can't do it there as the pagetable is not setup yet and you're probably
getting a #PF on any of the derefs down the static_key_enable() path.
I guess one possible place to enable the static key would be in
mem_encrypt_init() where everything should be set up already.
