s390/ipl: fix ipl with -no-reboot
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 resets" as special.

Fixes: a30fb811cbe9 (s390x: refactor reset/reipl handling)
