kexec/kdump as well as the bootloader use a subcode of diagnose 308
that is supposed to reset the I/O subsystem but not comprise a full
"reboot". With the latest refactoring this is now broken when
-no-reboot is used or when libvirt acts on a reboot QMP event, for
example a virt-install from iso images.
We need to mark these "subsystem reset" as special.

Looks sane to me, but I did not dig too deep and this
ain't code I'm particularly familiar with.
