[CRYPTO] scatterwalk: Add scatterwalk_map_and_copy
This patch adds the function scatterwalk_map_and_copy which reads or writes a chunk of data from a scatterlist at a given offset. It will be used by authenc which would read/write the authentication data at the end of the cipher/plain text. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
