From: Stefan Hajnoczi <stefa...@redhat.com>
The VirtQueueElement struct is serialized during migration but the
in_sg[]/out_sg[] iovec arrays are not usable on the destination host
because the pointers are meaningless.
Use virtqueue_map_sg() to refresh in_sg[]/out_sg[] to valid pointers
based on in_addr[]/out_addr[] hwaddrs.
