vhost-user-blk: set config ops before vhost-user init

Browse source 
As soon as vhost-user init is done, the backend may send
VHOST_USER_SLAVE_CONFIG_CHANGE_MSG, so let's set the
notification callback before it.

Also, it will be used to know whether the device supports
the config feature to advertize it or not.
