As qemu will only send VHOST_USER_SET_VRING_ENABLE message for guest
enabled vrings (only first queue pair will be enabled at initialized
stage), this will cause trouble for multiqueue case, vDPA's dev_conf
callback will get no chance be invoked. Decouple the dev_conf callback from
VHOST_USER_SET_VRING_ENABLE solves this issue.
