The error should not be emitted if "no_reboot && reason !=
SHUTDOWN_CAUSE_SUBSYSTEM_RESET" (the condition has changed a bit in
latest QEMU but the idea is the same).
This is because whoever invoked QEMU could already know about this
SEV-ES limitation, and use -no-reboot (aka -action reset=shutdown in
6.0) in order to change the forbidden warm reset into a shutdown+restart
cold reset.
