Subject: drm/i915/guc: Flush directly in log unregister

References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
Having both guc_flush_logs and guc_log_flush functions is confusing.
While we could just rename things, guc_flush_logs implementation is
quite simple. Let's get rid of it and move its content to unregister.
