[libvirt PATCH v2 5/5] conf: stop ignoring <loader>/<nvram> with firmware auto-select

Currently if the <os> firmware attribute is set then we silently ignore most of the <loader> and <nvram> element configs. This changes the code so that we always fully parse the <loader> and <nvram> but then use a post-parse method to explicitly reject invalid combinations.
