Avihai Horon 29d81b71aa vfio/migration: Block multiple devices migration
Currently VFIO migration doesn't implement some kind of intermediate
quiescent state in which P2P DMAs are quiesced before stopping or
running the device. This can cause problems in multi-device migration
where the devices are doing P2P DMAs, since the devices are not stopped
together at the same time.

Until such support is added, block migration of multiple devices.
