crypto: mxs-dcp - fix source scatterlist length access

In the Linux kernel, the following vulnerability has been resolved:

crypto: mxs-dcp - fix source scatterlist length access

mxs_dcp_aes_block_crypt() uses sg_dma_len() without mapping the source
scatterlist with dma_map_sg() first. Therefore, sg_dma_len() is invalid
and could return zero or a stale DMA length, causing encryption and
decryption to process the wrong number of bytes when
CONFIG_NEED_SG_DMA_LENGTH=y.

Use the original scatterlist length instead.
