Monitor: Convert simple handlers to cmd_new_ret()
The following handlers always succeed and hence can be converted to cmd_new_ret() in the same commit. - do_stop() - do_quit() - do_system_reset() - do_system_powerdown() - do_migrate_cancel() - do_qmp_capabilities() - do_migrate_set_speed() - do_migrate_set_downtime() Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
