[Qemu-devel] [PULL 5/8] runstate/migrate: Two more transitions

[Dr. David Alan Gilbert (git)]

From: "Dr. David Alan Gilbert" <address@hidden>

There's a race if someone does a 'stop' near the end of migrate;
the migration process goes through two runstates:
    'finish migrate'
    'postmigrate'

If the user issues a 'stop' between the two we end up with invalid
state transitions.
Add the transitions as valid.
