crypto: talitos - fix AEAD processing.

Browse source

This driver is working well in 'simple cases', but as soon as
more exotic SG lists are provided (dst different from src,
auth part not in a single SG fragment, ...) there are
wrong results, overruns, etc ...

This patch cleans up the AEAD processing by:
- Simplifying the location of 'out of line' ICV
- Never using 'out of line' ICV on encryp
- Always using 'out of line' ICV on decrypt
- Forcing the generation of a SG table on decrypt
