In case of NUMA reallocation, the virtqueue struct is reallocated
on another socket, meaning that its address changes.
In translate_ring_addresses(), addr pointer was not fetched again
after the reallocation, so it pointed to freed memory.
This patch just fetch again addr pointer after the reallocation.
