Log Message: ----------- virtio-mmio: Use the vmdev IO region for vq_ring.desc

The metal_io_region in the virtqueue struct is for translating the buffer address stored in the virtqueue descriptor table, not the address of the descriptor table itself.

This may have worked previously if the vring descriptors where part of the same IO space as the buffers they point to, but this is not guaranteed to always be the case. Fix that here.

Log Message: ----------- virtqueue: Fix comment on shm_io and fix type

This should hold a pointer to a metal_io_region, make that the type.

Also fix the comment above this variable. This region holds the address of the message buffers, not the vring descriptor table nor available/used ring data. It is only used for virt-to-phys/phys-to-vert translation on the buffers pointed to by these descriptors.
