tls: use tls_cipher_desc to simplify do_tls_getsockopt_conf
Every cipher uses the same code to update its crypto_info struct based on the values contained in the cctx, with only the struct type and size/offset changing. We can get those from tls_cipher_desc, and use a single pair of memcpy and final copy_to_user.
