drm: always check the repaint_status in update_complete 

Initially finish_frame() was never called in drm_output_update_complete() for
'dpms_off_pending = true'. This is wrong for repaint_status ==
REPAINT_AWAITING_COMPLETION and that was fixed in
68d49d772c ("compositor-drm: run finish_frame when
dpms is turned off in update_complete").
However finish_frame() may now be called for repaint_status !=
REPAINT_AWAITING_COMPLETION, which is not allowed and results in a failed
assertion.

Fix this by checking dpms and repaint_status unconditionally.
