So far, we used a dedicated dma pool to copy the result of outer IV for
cipher requests. Instead of using a dma pool per outer data, we prefer
use the op dma pool that contains all part of the request from the SRAM.
Then, the outer data that is likely to be used by the 'complete'
operation, is copied later. In this way, any type of result can be
retrieved by DMA for cipher or ahash requests.
