IPL over a virtio-scsi device requires special handling not available in the real architecture. For this purpose the IPL type 0xFF has been chosen as means of communication between QEMU and the pc-bios. However, a guest OS could be confused by seeing an unknown IPL type. This change sets the IPL parameter type to 0x02 (CCW) to prevent this. Pre-existing Linux has looked up the IPL parameters only in the case of FCP IPL. This means that the behavior should stay the same even if Linux checks for the IPL type unconditionally.
