[libvirt] [PATCHv2 2/2] conf: Swap order of AddImplicitControllers and DomainDefPostParse



Implicit controllers may be dependent on device definitions altered
in a post-parse callback. Specifically, if a console device is
defined without the target type, the type will be set in QEMU's
callback. In the case of s390, this is virtio, which requires
an implicit virtio-serial controller.
