qxl: hook monitors_config updates into crtc, not encoder.

Browse source

The encoder callbacks are only called in case the video mode changes.
So any layout changes without mode changes will go unnoticed.

Add qxl_crtc_update_monitors_config(), based on the old
qxl_write_monitors_config_for_encoder() function.  Hook it into the
enable, disable and flush atomic crtc callbacks.  Remove monitors_config
updates from all other places.
