[EXTERNAL] [PATCH] vhost: make cryptodev support optional

[Akhil Goyal]

> The vhost crypto part has seen CVEs in the past and is getting a lot of
> eyes those days.
> 
> Contrary to the vhost async datapath code, the cryptodev code seems to
> have active contributors, so dropping this code does not seem a good
> thing.
> 
> This change here allows to keep this support, yet disable it for
> uninterested parties.
