Subject: pvscsi: ring_desc do not have to be page aligned

pvscsi: ring_desc do not have to be page aligned

In contrast to other allocations made by pvscsi_init_rings(),
ring_desc is only used internally by SeaBIOS (not passed to
device-controller) and there is not restriction which force
it to be page aligned.
