vdpa: move vhost_vdpa_set_vring_ready to the caller
Doing that way allows CVQ to be enabled before the dataplane vqs,
restoring the state as MQ or MAC addresses properly in the case of a
migration.

The patch does it by defining a ->load NetClientInfo callback also for
dataplane.  Ideally, this should be done by an independent patch, but
the function is already static so it would only add an empty
vhost_vdpa_net_data_load stub.
