Herbert Xu 5fa0fea274 [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.
