[libvirt] [PATCH 04/14] 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.
