This patchset fixes use-after-free bugs which show up if you put
some of the hppa pci-host devices through an "init -> deinit" lifecycle,
as the device-introspect-test does.
The problem in both cases is that we were calling pci_register_root_bus()
in instance_init: we should only call this in realize, as all the
other callers do.
These bugs show up if you run 'make check' with an ASAN enabled
build; they are also likely behind the intermittent segfaults
on s390 that RTH has noticed recently.
