hw/virtio/vhost-backend: Fix Coverity CID 1432871
Fix uninitialized value issues reported by Coverity:
Field 'msg.reserved' is uninitialized when calling write().
While the 'struct vhost_msg' does not have a 'reserved' field,
we still initialize it to have the two parts of the function
consistent.
Reported-by: Coverity (CID 1432864: UNINIT)
Fixes: c471ad0e9bd ("vhost_net: device IOTLB support")
