crypto: shash - fold shash_digest_unaligned() into crypto_shash_digest()
Fold shash_digest_unaligned() into its only remaining caller. Also,
avoid a redundant check of CRYPTO_TFM_NEED_KEY by replacing the call to
crypto_shash_init() with shash->init(desc). Finally, replace
shash_update_unaligned() + shash_final_unaligned() with
shash_finup_unaligned() which does exactly that.
