stable inclusion from linux-4.19.207 commit c27cabac4afe8ca3822178888613499accb06920
--------------------------------
[ Upstream commit fe28140b3393b0ba1eb95cc109f974a7e58b26fd ]
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.
