crypto: skcipher - remove crypto_skcipher::keysize
Due to the removal of the blkcipher and ablkcipher algorithm types, crypto_skcipher::keysize is now redundant since it always equals crypto_skcipher_alg(tfm)->max_keysize. Remove it and update crypto_skcipher_default_keysize() accordingly. Also rename crypto_skcipher_default_keysize() to crypto_skcipher_max_keysize() to clarify that it specifically returns the maximum key size, not some unspecified "default".
