Also filter out non-migratable features out of host-passthrough
Also filter out non-migratable features out of host-passthrough

Commit de0aeaf filtered them out from the host-model features,
to allow host-model to be migratable by default.

Even though they are not passed to QEMU for host-passthrough,
(and not enabled by default) filter them out too
so the user does not think the domain has them.
