crypto: s5p-sss - use unregister_{ahashes,skciphers} in probe/remove

Replace multiple for loops with calls to crypto_unregister_ahashes() and
crypto_unregister_skciphers().

If crypto_register_skcipher() fails in s5p_aes_probe(), log the error
directly instead of checking 'i < ARRAY_SIZE(algs)' later.  Also drop
now-unused local index variables.  No functional changes.
