[PULL 36/56] Add helper to populate vhost-user message regions |

From: Raphael Norwitz <raphael.norwitz@nutanix.com>
When setting vhost-user memory tables, memory region descriptors must be
copied from the vhost_dev struct to the vhost-user message. To avoid
duplicating code in setting the memory tables, we should use a helper to
populate this field. This change adds this helper.
