virtio-crypto: fix memory leak in virtio_crypto_alg_skcipher_close_session()
[ Upstream commitb1d65f717c
] '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:0756ad15b1
