virtio-crypto: fix uninitialized variables

Though crypto_cfg.reserve is an unused field, let me
initialize the structure in order to make coverity happy.

*** CID 1365923:  Uninitialized variables  (UNINIT)
/hw/virtio/virtio-crypto.c: 851 in virtio_crypto_get_config()
845         stl_le_p(&crypto_cfg.mac_algo_h, c->conf.mac_algo_h);
846         stl_le_p(&crypto_cfg.aead_algo, c->conf.aead_algo);
847         stl_le_p(&crypto_cfg.max_cipher_key_len, c->conf.max_cipher_key_len);
848         stl_le_p(&crypto_cfg.max_auth_key_len, c->conf.max_auth_key_len);
849         stq_le_p(&crypto_cfg.max_size, c->conf.max_size);

       has been overridden by a builtin model.]
