crypto: talitos - Remove GFP_DMA and add DMA alignment padding 



GFP_DMA does not guarantee that the returned memory is aligned
for DMA.  It should be removed where it is superfluous.

However, kmalloc may start returning DMA-unaligned memory in future
so fix this by adding the alignment by hand.
