Two minor fixes for the virtio initialization that I spotted while
looking at the code. These currently do not fix any problem (since
QEMU is quite forgiving here when doing things wrong), but we should
anyway try to follow the virtio specification here.

pc-bios/s390-ccw/virtio:
Feature negotiation should be done first, since some fields in the
config area can depend on the negotiated features and thus should
rather be read afterwards.

PAPR 2.8 (2018) defines an extension to return 64bit value for

I suppose we don't negotiate any features that might affect the size of
