Subject: [PATCH] Paused domain should remain paused after migration

https://bugzilla.redhat.com/show_bug.cgi?id=981139

If a domain is paused before migration starts, we need to tell that to
the destination libvirtd to prevent it from resuming the domain at the
end of migration. This regression was introduced by commit 5379bb0.
