[PATCH 7.1 057/228] crypto: starfive - use scatterlist length before DMA mapping

7.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Thorsten Blum <[email protected]>

commit 6b36f13891ab4709b7d60023005176cdd5c368cf upstream.

Using sg_dma_len() is only valid after mapping a scatterlist with
dma_map_sg(). However, starfive_aes_aead_do_one_req() uses it before
mapping the scatterlist.

Use the original scatterlist length because the DMA length has not been
populated yet when CONFIG_NEED_SG_DMA_LENGTH=y.
