[Spice-devel] [PATCH xf86-video-qxl 1/2] Send correct count in qxl_update_monitors_config

[Hans de Goede]

When we've for example only output qxl-0 and qxl-2 enabled, the heads array
of the QxlMonitorsConfig struct we send will be sparse, containing a 0 width
and height entry at index 1. Since the qxl-dev (and subsequently the
spice-client) will only look at QxlMonitorsConfig.count entries in the heads
array (ignoring any 0x0 sized heads), the count must be 3 for this example
not 2 as we currently send.
