[PATCH 08/20] crypto: mediatek - use crypto_shash_tfm_digest()

[Eric Biggers]

From: Eric Biggers <ebigg...@google.com>

Instead of manually allocating a 'struct shash_desc' on the stack and
calling crypto_shash_digest(), switch to using the new helper function
crypto_shash_tfm_digest() which does this for us.
