We should not clear FLAGS_DMA_ACTIVE before omap_sham_update_dma_stop() is done calling dma_unmap_sg(). We already clear FLAGS_DMA_ACTIVE at the end of omap_sham_update_dma_stop(). The early clearing of FLAGS_DMA_ACTIVE is not causing issues as we do not need to defer anything based on FLAGS_DMA_ACTIVE currently. So this can be applied as clean-up.
