[Qemu-devel] [PATCH 22/25] monitor: Drop 'nb_args' from monitor_parse_command()

[Luiz Capitulino <lcapitulino@redhat.com>]

As far as I could understand nb_args is used to control additions
to the (already removed and size-fixed) args[] array.

As QDict is a dynamic data structure we don't need this.
