translate_ring_addresses and numa_realloc may change a virtio device and
virtio queue. Callers of those helpers must be extra careful and refresh
any reference to old data.
Change those functions prototype as a way to hint about this issue and
always ask for an indirect pointer.
Besides, when reallocating the device and queue, the code already made
sure it will return a pointer to a valid device. The checks on such
returned pointer can be removed.
