grant table errors with qemu-xen-traditional

[Olaf Hering <olaf@aepfle.de>]

I'm not sure if thats guest or host related, but current xen-unstable
with device_model_version="qemu-xen-traditional" fail to access the
block device properly, both PV and HVM are affected. The guest runs the
upcoming 12.2 kernel, which is based on forward ported xenlinux sources.

I added f7f8c33cd49885d69efc2e5f7f9a613d631762e2 to
qemu-xen-traditional, but that does not seem to help.

Any idea whats wrong?
