nbd: disallow nbd-server-add before nbd-server-start

Browse Source 
It works nicely with the QMP commands, but it adds useless complication
with HMP.  In particular, see the following:

    (qemu) nbd_server_add -w scsi0-hd0
    (qemu) nbd_server_start -a localhost:10809
    NBD server already exporting device scsi0-hd0
