[PATCH 5/6] crypto: skcipher - remove crypto_skcipher::decrypt

[Eric Biggers <ebiggers@kernel.org>]

From: Eric Biggers <ebiggers@google.com>

Due to the removal of the blkcipher and ablkcipher algorithm types,
crypto_skcipher::decrypt is now redundant since it always equals
crypto_skcipher_alg(tfm)->decrypt.

Remove it and update crypto_skcipher_decrypt() accordingly.
