crypto: img-hash - Fix dma_unmap_sg() nents value
[ Upstream commit 34b283636181ce02c52633551f594fec9876bec7 ]
The dma_unmap_sg() functions should be called with the same nents as the
dma_map_sg(), not the value the map function returned.
Fixes: d358f1abbf71 ("crypto: img-hash - Add Imagination Technologies hw hash accelerator")
