[Qemu-devel] [PULL 18/27] vl: Fix latent bug with -global and onboard devices

[Markus Armbruster <armbru@redhat.com>]

main() registers the user's -global only after we create the machine
object, i.e. too late for devices created in the machine's
.instance_init().

Fortunately, we know the bug is only latent: the commit before
previous fixed a bug that would've crashed any attempt to create a
device in an .instance_init().
