cryptodev: Use CryptoDevBackendOpInfo for operation

Move queue_index, CryptoDevCompletionFunc and opaque into struct
CryptoDevBackendOpInfo, then cryptodev_backend_crypto_operation()
needs an argument CryptoDevBackendOpInfo *op_info only. And remove
VirtIOCryptoReq from cryptodev. It's also possible to hide
VirtIOCryptoReq into virtio-crypto.c in the next step. (In theory,
VirtIOCryptoReq is a private structure used by virtio-crypto only)
