crypto: sahara - fix ahash selftest failure
[ Upstream commitafffcf3db9
] 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:5a2bb93f59
