Horia Geanta e11aa9f135 crypto: caam - fix DMA unmapping error in hash_digest_key 
Key being hashed is unmapped using the digest size instead of
initial length:

caam_jr ffe301000.jr: DMA-API: device driver frees DMA memory with different size [device address=0x000000002eeedac0] [map size=80 bytes] [unmap size=20 bytes]
