Fix error when reconnecting external display
Reconnecting an external display fails on initial
page-flip. This occurs when the pageflip_pending flag
has been set on the connector at the time the monitor
is removed. Once the connector's CRTC has been deallocated,
page_flip_handler cannot find the connector by its crtc_id,
so pageflip_pending will remain set. This causes
initialization to fail when the monitor is reconnected
with the error messages:
Skipping pageflip on output 'X'
Failed to initialize renderer on connector 'X': initial page-flip failed
To fix this problem, clear the pageflip_pending flag
when cleaning up the connector.
