Add missing vhost-user-blk help:

  $ qemu-storage-daemon -h
  ...
    --export [type=]vhost-user-blk,id=<id>,node-name=<node-name>,
             addr.type=unix,addr.path=<socket-path>[,writable=on|off]
             [,logical-block-size=<block-size>][,num-queues=<num-queues>]
                           export the specified block node as a
                           vhosts-user-blk device over UNIX domain socket
    --export [type=]vhost-user-blk,id=<id>,node-name=<node-name>,
             fd,addr.str=<fd>[,writable=on|off]
             [,logical-block-size=<block-size>][,num-queues=<num-queues>]
                           export the specified block node as a
                           vhosts-user-blk device over file descriptor
  ...

Fixes: 90fc91d50b7 ("convert vhost-user-blk server to block export API")
