crypto: nx - Moving NX-AES-GCM to be processed logic

The previous limits were estimated locally in a single step
basead on bound values, however it was not correct since
when given certain scatterlist the function nx_build_sg_lists
was consuming more sg entries than allocated causing a
memory corruption and crashes.

This patch removes the old logic and replace it into nx_sg_build_lists
in order to build a correct nx_sg list using the correct sg_max limit
and bounds.
