[EXTERNAL] [PATCH] cryptodev: reset resource pointers in init error path

[Akhil Goyal]

> cryptodev_cb_init() may free partially allocated resources on failure,
> but does not reset their pointers afterwards.
> 
> A later call to cryptodev_cb_cleanup() may then attempt to release both
> resources even when one of them has already been freed, because the
> cleanup logic does not rely on both pointers being valid independently.
> 
> Set freed pointers to NULL in the cryptodev_cb_init() error path to
> make subsequent cleanup safe.
