migration: allow unplug during migration for failover devices
In "b06424de62 migration: Disable hotplug/unplug during migration" we added a check to disable unplug for all devices until we have figured out what works. For failover primary devices qdev_unplug() is called from the migration handler, i.e. during migration. This patch adds a flag to DeviceState which is set to false for all devices and makes an exception for PCI devices that are also primary devices in a failover pair.
