crypto: omap-sham - clear dma flags only after omap_sham_update_dma_stop()



[ 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.
