Revert "vhost-user: add support reconnect for vhost-user ports"

This reverts commit edaf4ebe.

This uses "reconnect" as attribute for <source> element, but we already
have a <reconnect> element for <source> element for chardev devices.

Since this is the same feature for different device it should be
presented in XML the same way.

       vhost-user requires the virtio model type, thus the
       <code>&lt;model&gt;</code> element is mandatory.
-      <span class="since">Since 3.7.0</span> the element has an optional
-      attribute <code>reconnect</code> which configures reconnect timeout
-      (in seconds) if the connection is lost.
