Dr. David Alan Gilbert 3e996cc583 Fix virtio migration ... I misunderstood the vmstate macro definition when I reworked the virtio .get/.put. The VMSTATE_STRUCT_VARRAY_KNOWN, was described as being for "a variable length array (i.e. _type *_field) but we know the length". However it actually specified operation for arrays embedded in the struct (i.e. _type _field[]) since it lacked the VMS_POINTER flag. This caused offset calculation to be completely off, examining and potentially sending random data instead of the VirtQueue content. Replace the otherwise unused VMSTATE_STRUCT_VARRAY_KNOWN with a VMSTATE_STRUCT_VARRAY_POINTER_KNOWN that includes the VMS_POINTER flag (so now actually doing what it advertises) and use it in the virtio migration code. Fixes and description as per Sascha's suggestions/debug.
