Since device state transfer via multifd channels requires multifd
channels with packets and is currently not compatible with multifd
compression add an appropriate query function so device can learn
whether it can actually make use of it.

Nit: maybe rename to multifd_device_state_supported or
migration_multifd_device_state_supported, as it's specifically related to
multifd?
Sure, will do.
Thanks.
