crypto: sahara - fix ahash selftest failure

update() calls should not modify the result buffer, so add an additional
check for "rctx->last" to make sure that only the final hash value is
copied into the buffer.

Fixes the following selftest failure:
alg: ahash: sahara-sha256 update() used result buffer on test vector 3,
cfg="init+update+final aligned buffer"

Fixes: 5a2bb93f5992 ("crypto: sahara - add support for SHA1/256")
