virtio-crypto: fix memory leak in virtio_crypto_alg_skcipher_close_session()

Browse source

[ Upstream commit b1d65f717c ]

'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.
