crypto: sun8i-ce - fix nents passed to dma_unmap_sg()

Browse Source 
In sun8i_ce_cipher_unprepare(), dma_unmap_sg() is incorrectly called with
the number of entries returned by dma_map_sg(), rather than using the
original number of entries passed when mapping the scatterlist.

To fix this, stash the original number of entries passed to dma_map_sg()
in the request context.
