kms/impl-device: Process pending update from _schedule_process

Browse Source 
If ensure_deadline_timer_armed fails and crtc_frame->pending_update is
non-NULL, we need to process the pending update, or it may fall through
the cracks, and this stage view may freeze.

v2:
* Don't return immediately after calling
  meta_kms_impl_device_do_process_update. (Sebastian Wick)
v3:
* Call meta_kms_impl_device_do_process_update only if
  is_using_deadline_timer returned true, and log a warning if
  crtc_frame->pending_update is non-NULL otherwise.
