[Qemu-devel] [PATCH v2 1/9] vl: export machine_init_done

[Peter Xu <peterx@redhat.com>]

We have that variable but not exported.  Export that so modules can have
a way to poke on whether machine init has finished.

Meanwhile, set that up even before calling the notifiers, so that
notifiers who may depend on this field will get a correct answer.
