pc-bios/s390-ccw: Allow booting in case the first virtio-blk disk is bad
If you try to boot with two virtio-blk disks (without bootindex), and
only the second one is bootable, the s390-ccw bios currently stops at
the first disk and does not continue booting from the second one. This
is annoying - and all other major QEMU firmwares succeed to boot from
the second disk in this case, so we should do the same in the s390-ccw
bios, too.
