pc-bios/s390-ccw: Break up virtio-scsi read into multiples
A virtio-scsi request that goes through the host sd driver and exceeds
the maximum transfer size is automatically broken up for us. But the
equivalent request going to the sg driver presumes that any length
requirements have already been honored.
Let's use the max_sectors field on the virtio-scsi controller device,
and break up all requests (both sd and sg) to avoid this problem.
