qemu_migration: check for interface type 'hostdev'

Browse Source 
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.
