[dpdk-dev] [PATCH v3] cryptodev: fix check related to device id

[Akhil Goyal]

> 
> Each cryptodev are indexed with dev_id in the global rte_crypto_devices
> variable. nb_devs is incremented / decremented each time a cryptodev is
> created / deleted. The goal of nb_devs was to prevent the user to get an
> invalid dev_id.
> 
> Let's imagine DPDK has configured N cryptodevs. If the cryptodev=1 is
> removed at runtime, the latest cryptodev N cannot be accessible, because
> nb_devs=N-1 with the current implementaion.
> 
> In order to prevent this kind of behavior, let's remove the check with
> nb_devs and iterate in all the rte_crypto_devices elements: if data is
> not NULL, that means a valid cryptodev is available.
> 
> Also, remove max_devs field and use RTE_CRYPTO_MAX_DEVS in order to
> unify the code.
> 
> Fixes: d11b0f30df88 ("cryptodev: introduce API and framework for crypto
> devices")
