commit 4f2d90a7849fafebc74dec608f9b4ffa9400d1a6
Author: Frediano Ziglio <fziglio at redhat.com>

    red-qxl: Make sure we have at least one monitor
    
    It does not make sense to have a graphic card without a monitor.
    In spice_qxl_set_max_monitors we prevent to set 0 monitors, do
    the same in spice_qxl_set_device_info.
    
    This fixes https://bugzilla.redhat.com/show_bug.cgi?id=1691721.
