crypto: sahara - do not resize req->src when doing hash operations
[ Upstream commit a3c6f4f4d249cecaf2f34471aadbfb4f4ef57298 ]
When testing sahara sha256 speed performance with tcrypt (mode=404) on
imx53-qsrb board, multiple "Invalid numbers of src SG." errors are
reported. This was traced to sahara_walk_and_recalc() resizing req->src
and causing the subsequent dma_map_sg() call to fail.
Now that the previous commit fixed sahara_sha_hw_links_create() to take
into account the actual request size, rather than relying on sg->length
values, the resize operation is no longer necessary.
Therefore, remove sahara_walk_and_recalc() and simplify associated logic.
