drm/msm: dpu: Only check flush register against pending flushes [ Upstream commit 5f79e03b1f7c1b2cf0019ce6365fe5d52629813d ] There exists a case where a flush of a plane/dma may have been triggered & started from an async commit. If that plane/dma is subsequently disabled by the next commit, the flush register will continue to hold the flush bit for the disabled plane. Since the bit remains active, pending_kickoff_cnt will never decrement and we'll miss frame_done events. This patch limits the check of flush_register to include only those bits which have been updated with the latest commit.
