pc-bios/s390-ccw/virtio-blkdev: Remove virtio_assume_scsi()
The virtio_assume_scsi() function is very questionable: First, it is only called for virtio-blk, and not for virtio-scsi, so the naming is already quite confusing. Second, it is called if we detected a "invalid" IPL disk, trying to fix it by blindly setting a sector size of 512. This of course won't work in most cases since disks might have a different sector size for a reason. Thus let's remove this strange function now. The calling code can also be removed completely, since there is another spot in main.c that does "IPL_assert(virtio_ipl_disk_is_valid(), ...)" to make sure that we do not try to IPL from an invalid device.
