crypto: skcipher - remove crypto_skcipher::setkey

Due to the removal of the blkcipher and ablkcipher algorithm types,
crypto_skcipher::setkey now always points to skcipher_setkey().

Simplify by removing this function pointer and instead just making
skcipher_setkey() be crypto_skcipher_setkey() directly.
