Finally, complete the fully specified interface. msix_add_config() gets folded into msix_init() because we now have quite a few parameters to pass and rolling it in let's us error earlier, avoiding the ugly unwind exit path. msix_mmio_setup() also gets rolled in, just because it's redundant to rediscover offsets when we already have them for such a tiny function.
