[libvirt] [PATCH v4 03/30] conf: Run devicePostParse() again for the first serial device

The devicePostParse() callback is invoked for all devices so that drivers have a chance to set their own specific values; however, virDomainDefAddImplicitDevices() runs *after* the devicePostParse() callbacks have been invoked and can add new devices, in which case the driver wouldn't have a chance to customize them. Work around the issue by invoking the devicePostParse() callback after virDomainDefAddImplicitDevices(), only for the first serial devices, which might have been added by it. The same was already happening for the first video device for the very same reason. This will become important later on, when we will change virDomainDefAddConsoleCompat() not to set a targetType for automatically added serial devices.
