virtio-crypto: fix memory leak in virtio_crypto_alg_skcipher_close_session()
'vc_ctrl_req' is alloced in virtio_crypto_alg_skcipher_close_session(),
and should be freed in the invalid ctrl_status->status error handling
case. Otherwise there is a memory leak.
Fixes: 0756ad15b1fe ("virtio-crypto: use private buffer for control request")
