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
...
