[PATCH] qemu_migration: check for interface type 'hostdev'

When we try to migrate vm, we check if it contains only devices that are able to migrate. If a hostdev device is not able to migrate we raise an error with <hostdev/>, but it can actually be <interface/>, so we need to check if hostdev device was created by us from interface and show the right error message.
