crypto: crypto4xx - Call dma_unmap_page when done
In crypto4xx_cipher_done, we should be unmapping the dst page, not
mapping it.
This was flagged by a sparse warning about the unused addr variable.
While we're at it, also fix a sparse warning regarding the unused
ctx variable in crypto4xx_ahash_done (by actually using it).
Fixes: 049359d65527 ("crypto: amcc - Add crypt4xx driver")
