crypto: caam - fix aead sglen for case 'dst != src'
For aead case when source and destination buffers are different,
there is an incorrect assumption that the source length includes the ICV
length. Fix this, since it leads to an oops when using sg_count() to
find the number of nents in the scatterlist:
Unable to handle kernel paging request for data at address 0x00000004

While here, add a tcrypt mode for making it easy to test authenc
(needed for triggering case above).
