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()

>>> CID 1365923: Uninitialized variables (UNINIT)

is uninitialized when calling "memcpy".

has been overridden by a builtin model.]
