For preparing decryption request, several memory chunks are required (aead_req, sgin, sgout, iv, aad). For submitting the decrypt request to an accelerator, it is required that the buffers which are read by the accelerator must be dma-able and not come from stack. The buffers for aad and iv can be separately kmalloced each, but it is inefficient. This patch does a combined allocation for preparing decryption request and then segments into aead_req || sgin || sgout || iv || aad.
