[Libvir] PATCH: Fix virtual neworks with xm driver

The virtual networks stuff was never added to the xm driver for Xen 3.0.3 or earlier. This means that if adding a virtual network the bridge device won't get defined in the config. This patch addreses this, and also fixes a tiny mem leak in the equivalent code in the xend driver.
