crypto: starfive - use scatterlist length before DMA mapping

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.
