[PATCH] crypto: eip93 - Fix dma_unmap_single() direction in eip93_hash_handle_result()

[Thomas Fourier]

The buffer rctx->sa_record_base was mapped in eip93_hash_update();
rctx->sa_state_ctr_base and rctx->sa_state_base in eip93_send_req()
with direction DMA_TO_DEVICE but unmap with DMA_FROM_DEVICE in
eip93_hash_handle_result() and eip93_handle_result().

Change the unmap to match the mapping.
