Doing so is smarter than just appending them, because it takes the
controller index into account and will prevent problematic situations
such as a PCI Bridge being listed before the PCI controller it's
supposed to be plugged into, which QEMU can't cope with.
Although the QEMU command line for affected guests will be altered,
none of the changes should impact the guest ABI.
ACK as long as it doesn't mess up migration (I guess we need to find
some config that already works, but changes the ordering with the new
code, and make sure it can be migrated from old->new. Or we could assume
that 1) we believe it isn't a problem, and 2) in practice most things
that would be re-ordered wouldn't have worked at all without the
re-ordering, so it's a non-issue).
