crypto: skcipher - un-inline encrypt and decrypt functions
crypto_skcipher_encrypt() and crypto_skcipher_decrypt() have grown to be
more than a single indirect function call. They now also check whether
a key has been set, and with CONFIG_CRYPTO_STATS=y they also update the
crypto statistics. That can add up to a lot of bloat at every call
site. Moreover, these always involve a function call anyway, which
greatly limits the benefits of inlining.
So change them to be non-inline.
