We can ignore calls to monitor_vprintf() in QMP mode and use
monitor_puts() directly in monitor_json_emitter().

This allows us to drop this ugly hack.

In order to implement the new error handling and debugging
mechanism for command handlers, we need to change the cmd_new()
callback to return a value.

This commit introduces cmd_new_ret(), which returns a value and
will be used only temporarily to handle the transition from
cmd_new().

That is, as soon as all command handlers are ported to cmd_new_ret(),
it will be renamed back to cmd_new() and the new error handling
and debugging mechanism will be added on top of it.

net_check_clients() prints this when an VLAN has host devices, but no
guest devices.  It uses VLANState members nb_guest_devs and
nb_host_devs to keep track of these devices.  However, -device does
not update nb_guest_devs, only net_init_nic() does that, for -net nic.

Check the VLAN clients directly, and remove the counters.
