[PATCH 9/9] vhost-user: Report to front-end we support VHOST_USER_PROTOCOL_F_DEVICE_STATE

[Laurent Vivier <lvivier@redhat.com>]

Report to front-end that we support device state commands:
VHOST_USER_CHECK_DEVICE_STATE
VHOST_USER_SET_LOG_BASE

These feature is needed to transfer backend state using frontend
channel.
